Background/Objectives: A heterozygous mutation in the WFS1 gene is responsible for autosomal dominant non-syndromic hearing loss (DFNA6/14/38) and Wolfram-like syndrome, which is characterized by bilateral sensorineural hearing loss with optic atrophy and/or diabetes mellitus. However, detailed clinical features for the patients with the heterozygous p.A684V variant remain unknown. Methods: We report the clinical details of 14 cases with a heterozygous p.A684V variant in the WFS1 gene identified from target resequencing analysis of 63 previously reported deafness genes by next-generation sequencing of 15,684 hearing loss patients (mean age 27.5 ± 23.1 years old, 6574 male, 8612 female and 498 for whom information was unavailable). Results: Among the 14 patients from 13 families with the p.A684V variant, nine were sporadic cases. In addition, we confirmed de novo occurrence of this variant in seven families. This result strongly supports the notion that this variant was located on a mutational hotspot. When comparing previously reported cases of autosomal dominant WFS1 gene-associated hearing loss, most of the patients in this study showed severe-to-profound bilateral sensorineural hearing loss (genotype–phenotype correlation). Two patients had optic atrophy, while the others did not have any other complications. Conclusions: The identified heterozygous p.A684V variant appears to be a hotspot mutation and likely to cause severe-to-profound hearing loss in early childhood. Cochlear implantation is considered favorable in cases of hearing impairment due to this variant. [ABSTRACT FROM AUTHOR]

Background and Aim: Individuals who suffer Hearing Loss (HL) from inefficient auditory input will experience difficulty in phonological processing and reading. This study aimed to investigate the phonological processing and word and non-word reading abilities of Farsispeaking children with Cochlear Implants (CIs), Hearing Aids (HAs) and Normal Hearing (NH). Methods: Sixty-three children with severe to profound HL and NH who were in the first grade participated. Phonological Awareness (PA) and Phonological Working Memory (PWM) tests were used to assess phonological processing. Word and non-word reading abilities were assessed through reading and dyslexia tests reading abilities, phonological processing as well as the correlation between them were compared among three groups. Results: The PA, PWM and reading abilities of NH children were significantly different from children with HL (p<0.01). Correlations between words and non-words reading ability and some phonological processing tasks were observed in each of the three groups. Phonemic awareness for all three groups and intra-syllabic awareness for children with HA and NH were the most important predictors for word and non-word reading abilities. Conclusion: Hearing impairment had a critical effect on phonological processing as an important factor in word and non-word reading. [ABSTRACT FROM AUTHOR]

AbstractObjectivesDesignStudy SampleResultsConclusionsThe purpose of this study was to investigate a policy-related factor and patient-related factors that might affect hearing aid adoption for adults, specifically price unbundling, and demographic and audiologic factors, respectively.Retrospective data from hearing aid consultation appointments in an audiology clinic in a medical centre were examined. Appointments were conducted between 2019 and 2023, capturing visits when services and devices were charged using a model that was bundled (2019–2022) and unbundled (2023). In the unbundled model, a separate fee was charged for the consultation appointment.Adults (n = 5186) without hearing aid experience who completed a hearing aid consultation appointment.After unbundling, a higher percentage of consultation appointments resulted in hearing aid adoptions (increased from 53% to 65%), despite a decline in the number of hearing aid consultation appointments. The absolute number of hearing aid adoptions per provider did not change over time. Also stable were reasons for hearing aid non-adoption; they were primarily related to lack of perceived hearing difficulty.By unbundling and charging specifically for hearing aid consultation appointments, hearing aid consultations can be made more efficient, decreasing time spent with patients who do not need consultation services without negatively impacting revenue.

AbstractObjectiveDesign and study sampleResultsConclusionsThe relationship between aided speech recognition and hearing-aid (HA) amplification was investigated in a retrospective study.Pure-tone thresholds, aided and unaided speech recognition and real-ear measurements of 635 ears in 374 HA users were reviewed. Ears were classified according to pure-tone average (PTA) and real-ear aided response (REAR) in relation to the targets of NAL-NL2 and DSL v5.0.For DSL v5.0, compared with NAL-NL2, higher amplification was calculated almost consistently for input levels of 65 and 80 dB SPL. Speech-recognition scores were best when the REAR reached ±5 dB or exceeded 5 dB the DSL v5.0 target and were lowest when the REAR fell more than 5 dB below the NAL-NL2 target.The greatest impact of the REAR on speech recognition was observed at hearing losses between 50 and 80 dB HL. It was found that to optimise speech recognition and audibility for patients in this range HA fittings should target DSL v5.0 prescription values. For hearing losses below 50 dB HL, both NAL-NL2 and DSL v5.0 may be considered for HA fitting. However, for hearing losses above 80 dB HL, aided speech recognition is insufficient in most cases.

Many auditory system functions improve under the influence of music. The binaural hearing also plays a critical role in speech-in-noise perception. The present study was done to investigate the effect of music on speech-in-noise perception in binaural and monaural hearing aid users. This study was conducted on 40 unilateral and bilateral hearing aid users aged 25 to 55, including 23 female and 17 male individuals. The Q-SIN test and SSQ questionnaire were used to investigate the effect of music on speech-in-noise perception before and after the treatment. Results of the Q-SIN test showed that music reduced SNR-50 and SNR LOSS, which was more evident in bilateral hearing aid users (p < 0.05). Results of the SSQ questionnaire also indicated that after the 3-month reevaluation, the questionnaire scores increased, and the increase was higher in the bilateral hearing aid users (p < 0.05). Regularly listening to music on a programmed basis improves speech-in-noise perception. Results of the present study showed that bilateral hearing aids had a higher effect on improving speech-in-noise perception than unilateral hearing aids. [ABSTRACT FROM AUTHOR]

Despite the significant advancements in hearing aid technology, their adoption rates remain low, with stigma continuing to be a major barrier for many. This review aims to assess the origins and current state of hearing aid stigma, as well as explore potential strategies for alleviating it. This review examines the societal perceptions, psychological impacts, and recent technological advancements that can influence hearing aid adoption and reduce stigma. Methods: A narrative-focused review of the literature from peer-reviewed journals and reputable sources was conducted, analyzing papers on hearing aid stigma, adoption rates, and technological solutions. The research works were categorized based on their focus on the drivers and alleviation strategies for the stigma of hearing aids. Results: This review identifies stigma as a complex, multifaceted issue driven primarily by ageism, disability perception, and the association of hearing aids with aging and incapability. Despite technological improvements, the studies surveyed listed stigma as a major factor in non-adoption. Technological advancements such as artificial intelligence in sound processing, multifunctional features, and innovative design have shown potential in reducing stigma and improving user experience. Conclusions: Alleviating the stigma of hearing aids requires a multi-pronged approach, combining improvements in technology with changes in societal perceptions. Multifunctional devices including both health and communications functions, advanced signal processing, and esthetic improvements can drive their adoption, but broader public health awareness and education are also essential to changing societal attitudes and fostering greater acceptance of hearing aids.

Auditory neuropathy spectrum disorder (ANSD) is often missed by standard hearing tests, accounting for up to 10% of hearing impairments (HI) and commonly linked to variants in 23 genes. We assessed 122 children with HI, including 102 with sensorineural hearing loss (SNHL) and 20 with ANSD. SNHL patients were genotyped for common GJB2 variants using qPCR, while ANSD patients underwent whole exome sequencing, with variants analyzed across 249 genes. Homozygous GJB2 variants were found in 54.9% of SNHL patients. In 60% of ANSD patients, variants were detected in OTOF (25%), CDH23, TMC1, COL11A1, PRPS1, TWNK, and HOMER2 genes, including eight novel variants. Transient evoked otoacoustic emissions testing revealed differences at 4000 Hz (p = 0.0084) between the ANSD and SNHL groups. The auditory steady-state response (ASSR) test showed significant differences at 500 Hz (p = 2.69 × 10−4) and 1000 Hz (p = 0.0255) compared to pure-tone audiometry (PTA) in ANSD patients. Our questionnaire shows that the parents of children with SNHL often report an improved quality of life with hearing aids or cochlear implants, while parents of children with ANSD frequently experience uncertainty about outcomes (p = 0.0026), leading to lower satisfaction.

Purpose: Hearing aid fitting can be challenging when tinnitus accompanies hearing loss, as speech intelligibility and quality of life are affected by both hearing loss and tinnitus perception. However, studies focusing on the optimal hearing aid fitting for this group are scarce. Here, we aim to investigate the performance of alternative hearing aid fitting scenarios in improving hearing aid benefit and managing tinnitus. Methods: Sixty-six participants were included in the study and randomly divided into three groups based on the fitting formula: NAL-NL2, DSL pediatric and hybrid gain fitting procedure (covering NAL-NL2 for low frequencies and DSL pediatric formulas for high frequencies). Hearing aid benefit was evaluated using the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire and speech perception in noise (SPIN). To evaluate tinnitus perception, psychoacoustic characteristics of tinnitus were determined, and the Tinnitus Handicap Inventory (THI) was gathered. Results: The NAL-NL2 fitting procedure showed better results in hearing aid benefit and SPIN compared to the DSL pediatric procedure. In the DSL pediatric procedure, better results were obtained in tinnitus management compared to NAL-NL2. There was no difference between the hybrid fitting procedure and DSL pediatric in tinnitus management. The hybrid fitting procedure also did not differ from NAL-NL2 in SPIN and hearing aid benefit. Conclusion: Here, we propose a hybrid gain fitting procedure that can be a better alternative to boost hearing aid performance and tinnitus management in clinical practice. [ABSTRACT FROM AUTHOR]

Bone conduction systems are sometimes not well tolerated due to the tension on the skull. Therefore, a brand non-surgical device was developed, the ADHEAR (MED-EL, Innsbruck, Austria). It is based on a novel fixation system using an adhesive adapter, which allows for a more comfortable and efficient mechanical transmission of the acoustic signal and that can be used as treatment for conductive hearing loss. The purpose of the study is to evaluate the performance of ADHEAR in two patients with unilateral conductive hearing loss. An 8-years-old patient with external ear canal stenosis obtained a functional gain of 28.75 dB, while a 16-years-old patient with Goldenhar syndrome showed a recovery of 53.75 dB. Therefore, both cases suggest that ADHEAR appears to be an effective treatment for pediatric patients who due to the medical condition cannot be treated surgically or fitted with conventional hearing aids.

Background: Hearing loss (HL) among older adults is a major global health concern. Hearing aids (HAs) offer an effective solution to manage HL and enhance the quality of life. However, the adoption and the consistent use of HAs remain low, making non-use a significant barrier to successful audiological rehabilitation. The aim of the study was to assess the benefit of HAs among patients with different degrees of HL and to determine the profiles of patients who have the least benefit from HAs. Methods: the HA benefits were assessed by using the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. Participants were assigned to the study groups based on the pure-tone audiometry. This paper presents the results obtained by using HAs in various listening environments among 167 patients. Results: The majority of individuals benefited from HAs in a noisy environment while a reverberant environment provided the lowest benefit. It was observed that the degree of HL had a statistically significant impact on the benefits of HAs in terms of the communication ease, the reverberation, the background noise, and the global score. A moderately positive correlation was observed between the unaided APHAB and the HL degree. The subjects' APHAB scores ranged from the 50th to the 65th percentile. Additionally, women had a significantly better improvement than men. Conclusions: HAs improved communication in everyday life situations among 91.6% of HA users. The degree of HL influences APHAB scores. Patients with a severe degree of HL achieved the greatest APHAB scores while male patients with mild HL received the lowest benefits of HAs. Both HL and the age, gender, and HA type are factors that also play important roles. The APHAB questionnaire is a reliable screening test for patients with hearing difficulties.

Abstract Background We compared and analyzed the surgical results of fat myringoplasty between elderly and young adult patients with chronic otitis media. We also investigated whether underlying diseases and other factors impact the surgical outcome. Methods We retrospectively reviewed the data of 141 patients who underwent fat myringoplasty for chronic otitis media for five years. They were compared by age, sex, underlying disease, perforation size, pre- and postoperative pure tone audiometry, postoperative otorrhea, postoperative re-perforation, and cause of re-perforation. Result Postoperative re-perforation was more common in the elderly group, albeit with no significant difference (p = 0.072). The factors affecting re-perforation were insufficient fat graft (44.4%), postoperative infection (33.3%), and nasal blowing (22.2%). Our findings revealed no significant association between preoperative perforation size and re-perforation (p = 0.391). Additionally, we found no significant relationship between hypertension and re-perforation (p > 0.99), nor between age group and postoperative infection (p = 0.488). Diabetes was also not significant (p = 0.640). Following surgery, both groups exhibited a significant improvement in hearing. Conclusion Although age and underlying conditions play significant roles in the healing process, our results suggest that external factors such as infection, nasal blowing, cough, and insufficient grafted fat tissue have a similarly significant impact on surgical outcomes in elderly patients with COM as they do in adults. In conclusion, the decision to perform surgery in elderly patients with COM should be based on a comprehensive assessment of the patient’s overall health status, hearing, use of hearing aids, and the indications for surgery.

Abstract Purpose The specific objectives of this study were as follows: (1) to translate and adapt the English version of the International Outcome Inventory for Hearing Aids (IOI-HA) into Hindi, (2) to present data obtained from the hearing aid users, (3) and to investigate the effect of different factors on effective hearing aid use using the Hindi version of the IOI-HA. Method The English version of IOI-HA was translated to Hindi by three native Hindi speakers who were proficient in both Hindi and English and had Hindi as their first language. The Hindi version of IOI-HA along with a demographic questionnaire was given to 100 experienced hearing aid users who were literate and more than 18 years of age. Results The findings indicated 53% of individuals utilize their hearing aids for over 8 h daily, while 46% use them for 4 to 8 h a day. A greater number of participants experienced benefits from wearing their hearing aids, suggesting their overall effectiveness for users. Also, 64% of people said their HA was fulfilling their expectations. Sixty-seven percent of participants said life has become quite a lot better with HA usage. The results revealed that age, gender, and type of hearing loss showed no significant association with any test item. Conclusion The Hindi version of the IOI-HA has proven to be a valuable self-assessment tool for hearing aid users. It aids clinicians and audiological practitioners in comprehending the challenges faced by users and can offer guidance for counseling and assessing the benefits derived from hearing aids.

This systematic literature review explored the relationship between hearing loss, the use of hearing aids or cochlear implants, and late-deafened adults' perception and appreciation of, and participation in, music. To identify articles, four databases were searched, MEDLINE, Scopus, Embase, and American Psychological Association (APA) PsycINFO, using terms associated with hearing loss, hearing aids, cochlear implants, music perception, appreciation, or participation. The included studies were empirical, written in English, peer reviewed, used any research method, had no date restrictions, and involved late-deafened adults. A formal risk of bias evaluation was undertaken using the Joanna Briggs Institute (JBI) Critical Appraisal tools. A double-blind review of 2595 articles was completed in June 2023, with a total of 131 studies meeting the inclusion criteria. Typically, the reviewed articles focused on music perception testing. The studies included more than 6900 adult participants with hearing loss. Data relating to the review question were extracted and thematically coded. Only 18 studies reported on music experiences for adults who had hearing loss with or without hearing aids. The remaining 113 articles related to cochlear implant users, and 91 of these focused primarily on identification of musical structural components. The reviewed articles consistently established that hearing loss and hearing devices have a substantial, generally negative, impact on music perception. The psychosocial and emotional need for music was mostly overlooked, with few studies focusing on music appreciation, enjoyment, social connectedness, or participation. Further research is needed to understand the broader context of how hearing loss and hearing devices impact personal experiences including mental and physical well-being and quality of life.

The combination of piezoelectric ceramics with silicon nanomembranes can provide a unique combination of electronic and mechanical functionality. For example, an integrated remotely accessible sensor/actuator can serve as a sound transducer to be placed on the tympanic membrane of the human ear. Such an implant would enable direct sound transmission in the kHz range via down‐conversion of a modulated carrier signal at radio frequency. The viability of this concept is demonstrated via a specific design of the nanomembrane bonded over a hole in the piezoelectric chip as well as driving this chip to create a strong nonlinear mechanical response in the nanomembrane. The response in the audible‐frequency range and the result is demonstrated by modulating the piezoelectric chip with a C‐major audible tune—the tone ladder—and retrieving this sound by an optical readout method. Finally, to prove the possibility of remote actuation of the nanomembrane, an antenna on the chip is integrated and the wide‐band transmission from a mobile source is simulated. It is concluded that a remotely actuated invisible hearing aid is possible. [ABSTRACT FROM AUTHOR]

To address the performance and computational complexity issues in speech enhancement for hearing aids, a speech enhancement algorithm based on a microphone array and a lightweight two-stage convolutional recurrent network (CRN) is proposed. The algorithm consists of two main modules: a beamforming module and a post-filtering module. The beamforming module utilizes directional features and a complex time-frequency long short-term memory (CFT-LSTM) network to extract local representations and perform spatial filtering. The post-filtering module uses analogous encoding and two symmetric decoding structures, with stacked CFT-LSTM blocks in between. It further reduces residual noise and improves filtering performance by passing spatial information through an inter-channel masking module. Experimental results show that this algorithm outperforms existing methods on the generated hearing aid dataset and the CHIME-3 dataset, with fewer parameters and lower model complexity, making it suitable for hearing aid scenarios with limited computational resources.

AbstractObjectiveDesignStudy sampleResultsConclusionsExploring applications of automatic speech recognition and text-to-speech technologies in hearing assessment and evaluations of hearing aids.Review protocol was registered at the INPLASY database and was performed following the PRISMA scoping review guidelines. A search in ten databases was conducted in January 2023 and updated in June 2024.Studies that used automatic speech recognition or text-to-speech to assess measures of hearing ability (e.g. speech reception threshold), or to configure hearing aids were retrieved. Of the 2942 records found, 28 met the inclusion criteria.The results indicated that text-to-speech could effectively replace recorded stimuli in speech intelligibility tests, requiring less effort for experimenters, without negatively impacting outcomes (n = 5). Automatic speech recognition captured verbal responses accurately, allowing for reliable speech reception threshold measurements without human supervision (n = 7). Moreover, automatic speech recognition was employed to simulate participants’ hearing, with high correlations between simulated and empirical data (n = 14). Finally, automatic speech recognition was used to optimise hearing aid configurations, leading to higher speech intelligibility for wearers compared to the original configuration (n = 3).There is the potential for automatic speech recognition and text-to-speech systems to enhance accessibility of, and efficiency in, hearing assessments, offering unsupervised testing options, and facilitating hearing aid personalisation.

Introduction: Hearing aid (HA) manufacturers have introduced behind-the-ear (BTE) models where the microphone is positioned in the ear canal, which could impact auditory performance by distorting the pinna's acoustic cues. This study aimed to compare two different BTE HAs with varying microphone positions: the receiver in the ear (RITE) and the transducer in the ear (TIE). Methods: The study involved 10 participants who had never used HAs before. They used both RITE and TIE HAs bilaterally for 3 weeks. Auditory performance was assessed through free field hearing assessments (hearing thresholds, speech recognition threshold, and speech discrimination score), the Turkish Matrix Sentence Test (TURMatrix), a sound localization test, and the Satisfaction with Amplification in Daily Living (SADL) questionnaire. Results: There was no significant difference between TIE and RITE in the free field hearing assessments. However, TIE outperformed RITE in non-adaptive TURMatrix scores in quiet, adaptive TURMatrix scores in noise, and sound localization accuracy at various angles. SADL sub-scores (Positive Effect, Service and Cost, and Personal Image) and overall satisfaction scores were significantly better for TIE. Discussion: The microphone position in HAs can influence auditory performance. This study demonstrated that TIE provided better speech intelligibility, localization accuracy, and user satisfaction compared to RITE. [ABSTRACT FROM AUTHOR]

Objectives: The ability to localize sound sources is crucial for everyday listening, as it contributes to spatial awareness and the detection of warning signs. Individuals with hearing impairment have poorer localization abilities, which further deteriorate when they are fitted with a hearing aid. Although numerous studies have addressed this phenomenon, there is a lack of systematic evidence. The aim of the current systematic review is to address the following research question, "Do behavioural measures of spatial hearing ability improve with bilateral hearing aid fitting compared to the unaided hearing condition?" Design: A comprehensive search was conducted by two independent authors utilizing electronic databases, using various electronic databases, covering the period of 1965 to 2022. The inclusion and exclusion criteria were formulated using the Population, Intervention, Compression, Outcome, and Study design (PICOS) format, and the certainty of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines. Results: The comprehensive search resulted in 2199 studies, 17 studies for qualitative synthesis and 15 studies for quantitative synthesis. The collected data was divided into two groups, namely vertical and horizontal localization. The results of the quantitative analysis indicate that the localization performance was significantly better in the unaided condition for both vertical and horizontal planes. The certainty of our evidence was judged to be moderate, meaning that "we are moderately confident in the effect estimate. The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different". Conclusion: The review findings demonstrate that the bilateral fitting of the hearing aid did not effectively preserve spatial cues, which resulted in poorer localization performance irrespective of the plane of assessment. Review Registration: Prospective Register of Systematic Reviews (PROSPERO); CRD42022358164 IMPLICATIONS FOR REHABILITATION: Hearing aids are a widely used rehabilitative method to compensate for the loss of audibility in individuals with hearing impairment. The current review highlights that, even though hearing aids can enhance audibility, they often fail to preserve spatial cues. This review paper provides a comprehensive summary of the existing literature, focusing on the preservation of spatial cues by hearing aids and the technologies that can enhance localization performance to a certain degree. The findings of the current study encourage both researchers and hearing aid manufacturers to advance their research methods pertaining to the preservation of spatial cues. This advancement has the potential to improve spatial awareness and possibly improve speech perception in the presence of noise in hearing aid users. [ABSTRACT FROM AUTHOR]

AbstractPurposeMethodResultConclusionThe purpose of this review was to map speech intelligibility measures used for assessing d/Deaf and hard-of-hearing children onto the International Classification of Functioning, Disability and Health.This review considered perceptual speech intelligibility measures (Articulation functions b320) used to assess deaf and hard-of-hearing children aged 12 years and younger. The following electronic databases were searched: CINAHL; ERIC (ProQuest); Linguistic, Language, and Behaviour Abstracts; Scopus; Medline via PubMed; CENTRAL via Ovid; Cochrane via Ovid; and Joanna Briggs via Ovid. Data were extracted describing the article, participant, listener, study, speech intelligibility, and psychometric characteristics from the 245 included studies.Speech intelligibility was measured as articulation functions (b320) through speaking (d330) in all studies. Other Body Functions frequently measured were speech discrimination (b2304; 28%) and mental functions of language (b167; 27%). Activities and Participation factors other than speaking d330 were generally not considered. Speech intelligibility was most often measured in the context of health services (e5800; 66%).Previous research on the speech intelligibility of deaf and hard-of-hearing children has largely lacked a broader perspective of functioning. Clinicians and educators of deaf and hard-of-hearing children should consider Activities and Participation, Environmental, and Personal Factors when assessing speech intelligibility.

Background: We compared and analyzed the surgical results of fat myringoplasty between elderly and young adult patients with chronic otitis media. We also investigated whether underlying diseases and other factors impact the surgical outcome. Methods: We retrospectively reviewed the data of 141 patients who underwent fat myringoplasty for chronic otitis media for five years. They were compared by age, sex, underlying disease, perforation size, pre- and postoperative pure tone audiometry, postoperative otorrhea, postoperative re-perforation, and cause of re-perforation. Result: Postoperative re-perforation was more common in the elderly group, albeit with no significant difference (p = 0.072). The factors affecting re-perforation were insufficient fat graft (44.4%), postoperative infection (33.3%), and nasal blowing (22.2%). Our findings revealed no significant association between preoperative perforation size and re-perforation (p = 0.391). Additionally, we found no significant relationship between hypertension and re-perforation (p > 0.99), nor between age group and postoperative infection (p = 0.488). Diabetes was also not significant (p = 0.640). Following surgery, both groups exhibited a significant improvement in hearing. Conclusion: Although age and underlying conditions play significant roles in the healing process, our results suggest that external factors such as infection, nasal blowing, cough, and insufficient grafted fat tissue have a similarly significant impact on surgical outcomes in elderly patients with COM as they do in adults. In conclusion, the decision to perform surgery in elderly patients with COM should be based on a comprehensive assessment of the patient's overall health status, hearing, use of hearing aids, and the indications for surgery.

Background and Aim: Real-Ear-to-Coupler Difference (RECD) is affected by the type of transducer and its coupling method. This study aimed to investigate the effect of receiver type used in Receiver-in-Canal (RIC) hearing aids on RECD and Coupler Response for Flat Insertion Gain (CORFIG) obtained by the same coupling method. Methods: In this study, the right ears of 30 normal-hearing adults (25 men and 5 women, with a mean age of 28.13±5.62 years) were studied. We used the RIC hearing aids with two standard and power receivers. The foam of the ER-3A insert earphone was used as a coupling system in both receivers. By using the Audiogram Direct test within Phonak's fitting software, 70 dB HL intensity was produced at different frequencies, once in the realear and again in the HA-1 coupler. By assessing the difference between real-ear and HA-1 coupler measurements, the RECD was first obtained. Then, the CORFIG was obtained at different frequencies by subtracting the Microphone Location Effect (MLE) and RECD from Real-Ear Unaided Gain (REUG). Results: The RECD and CORFIG values obtained from the standard receiver at all frequencies were significantly different from those from the power receiver (p<0.05), where the use of the power receiver resulted in lower RECD and higher CORFIG. With the increase in frequency, the RECD increased. A small frequency changes of 50 Hz had a significant effect on RECD and CORFIG. Conclusion: The type of receiver used in RIC hearing aids has a significant effect on the RECD and CORFIG values. [ABSTRACT FROM AUTHOR]

Objective To determine the readability and quality of both English and Spanish Web sites for the topic of hearing aids. Study Design Cross-sectional Web site analysis. Setting Various online search engines. Methods The term "hearing aid" was queried across four popular search engines. The first resulted 75 English Web sites and first resulted 75 Spanish Web sites were extracted for data collection. Web sites that met the inclusion criteria were stratified by the presence of a Health on the Net Code (HONCode) certificate. Articles were then compiled to be independently reviewed by experts on hearing aids, using the DISCERN criteria, which allowed assessment of the quality of the Web sites. Readability was assessed by calculating the Flesch Reading Ease Score in English and the Fernandez Huerta Formula in Spanish. Readability and quality were both analyzed, comparing scores to their respective language and cross-comparing. Results There were 37 English Web sites and 30 Spanish Web sites that met inclusion criteria. When analyzing readability, English Web sites were determined to be significantly more difficult to read (average = 55.37, standard deviation [SD] = 7.73, 95% confidence interval [CI] = 52.9–57.9) than the Spanish Web site counterparts (average = 58.64, SD = 5.26, 95% CI = 56.8–60.5, p = 0.035). For quality, Spanish Web sites (average = 38, SD = 9.7, 95% CI = 34.5–41.5) were determined to be of significantly higher quality than English Web sites (average = 32.16, SD = 10.60, 95% CI = 29.7–34.6). Additionally, there was a significant difference between the non-HONCode English Web sites versus the non-HONCode Spanish Web sites (p = 0.0081), signifying that Spanish non-HONCode certified Web sites were less reliable than non-HONCode certified English Web sites. Discussion The present study highlights the importance and necessity of providing quality, readable materials to patients seeking information regarding hearing aids. This study shows that both English and Spanish Web sites are written at a level that is much higher than the American Medical Association (AMA)-recommended sixth-grade reading level, and no Web site included in this study fell at or below the AMA-recommended sixth-grade reading level. English and Spanish Web sites also lacked consistency and quality, as evidenced by their wide variability in DISCERN scores. Specifically, Hispanic patients are more likely to suffer long-term consequences of their health care due to low levels of health literacy. It is important to bridge this gap by providing adequate reading materials. It is especially important to provide evidence-based claims that are directly supported by experts in the field.

OBJECTIVE: To compare the score of the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S) quality of life questionnaire in older adult patients with hearing loss, before and three months after the adaptation of an external hearing aid. MATERIALS AND METHODS: An observational, analytical, prospective, longitudinal and prolective study including older adults who attended the Dr. Manuel Gea Gonzalez General Hospital, Mexico City, with hearing loss and who were candidates for hearing aid adaptation. The HHIE-S questionnaire was administered before and three months after the hearing aid fitting. The results obtained in the questionnaire were compared and the clinical and sociodemographic characteristics, the pattern of use and laterality of the hearing aids of the patients studied were described. RESULTS: There were included 18 patients. The results showed a significant improvement in the total score (28.8 vs 9.3), emotional (13.4 vs 4.5) and social (15.4 vs 4.7) before and three months after the placement of the hearing aid in the HHIE-S questionnaire (p = 0.001). The average age of the patients studied was 75.5 years and the majority were women. Most patients had a diagnosis of presbycusis (n = 16) and 9 reported a diagnosis of diabetes mellitus. CONCLUSIONS: The placement of hearing aids improves the quality of life in the social and emotional aspects of older adults with hearing loss. Therefore, it is of utmost importance to identify and treat hearing loss in older adults to impact the quality of life of these patients. [ABSTRACT FROM AUTHOR]

Hearing loss affects over 1.5 billion individuals globally, with significant implications for mental health. This study investigates the association between hearing aid use and mental health outcomes, by particularly focusing on depression and unmet mental health needs (UMHN), across a diverse international sample. Utilizing data from the third wave of the European Health Interview Survey (EHIS), this study involved 17,660 participants with hearing impairment from 28 countries. The study examined the association between hearing aid use and mental health outcomes, including the likelihood of moderate and severe depression and UMHN due to lack of contact with general practitioners (GPs) and mental health specialists. Logistic regression models, adjusted for socio-demographic characteristics, health risk behaviours, and other relevant variables, were employed. Inverse probability weights were used to mitigate potential selection bias. Hearing aid usage was associated with significantly lower likelihoods of moderate depression (Odds Ratio [OR] = 0.58, 95%CI = [0.54, 0.63]) and severe depression (OR = 0.61, 95%CI = [0.55, 0.69]), compared to non-usage. Hearing aid usage was also associated with reduced UMHN due to lack of GP contact for moderate (OR = 0.82, 95%CI = [0.75, 0.89]) and severe depression (OR = 0.75, 95%CI = [0.59, 0.95]). The depression risk reductions were greater among females and higher-educated subgroups but lower in individuals aged ≥65 years. Income level and rurality also impacted UMHN due to the lack of GP contact. No associations were found between hearing aids and UMHN due to the lack of mental health specialist contact. Hearing aid adoption showed protective associations against mood disorders and lowered unmet primary mental healthcare needs. Tailoring intervention strategies to vulnerable sociodemographic profiles could optimize mental health benefits among those with hearing loss. Integrating hearing health services within mental healthcare delivery frameworks is vital amidst the rising global burden. • There is little insight into hearing aids' impact on mental health and unmet mental health needs (UMHN). • Hearing aid use was associated with lower rates of depression and UMHN, bases on 17,000 participants from 28 countries. • The findings advocate for integrating hearing health into mental health frameworks.

Objective: This systematic review examined the audiological and non-audiological factors that influence hearing aid use, benefit and satisfaction in adults based on studies published during the last decade (2010 and 2023). Design: Studies were identified by using PRISMA guidelines for systematic searches on five platforms (Web of Science, Scopus, PubMed, EBSCOhost including CINAHL and Academic Search Complete). The National Institute of Health Quality assessment tool and the Oxford Centre for Evidence Based Medicine tool were used for quality assessment and grading of level of evidence. Results: Forty-six articles were included in the review. A total of 101 significant factors influencing hearing aid use (n = 47), benefit (n = 17) and satisfaction (n = 37) were identified. Clear determinants of hearing aid use, benefit and satisfaction included hearing sensitivity, self-reported hearing difficulty, speech perception, attitude and beliefs. 34 cross-sectional studies in this review were graded level 4, 9 cohort studies rated level 3, and 3 randomised control trials rated level 2. Conclusion: Factors associated with hearing aid outcomes identified in the past decade support previous evidence. New factors like social networks and service-delivery models, have also been identified. These factors require further investigations through high quality studies to further strengthen existing evidence. [ABSTRACT FROM AUTHOR]

Background: A delay in a child's capacity to develop language is one of the impacts of hearing loss. Children use amplification devices so they can develop spoken language skills comparable or equivalent to those of their peers without hearing loss. The aim of the study was to detect the effect of using different amplification devices on the development of the language in children. Methods: The study included three groups of 5-8 years old children, who used different hearing devices and had bilateral severe to profound sensorineural hearing loss. Each group consisted of ten children; one using binaural hearing aids, the second had a unilateral cochlear implant, and the third group received a bimodal fitting. They were submitted to the following: history taking, intelligence and mental status examination, auditory performance assessment, and Language assessment. Results: Bimodal and cochlear implant users have a significantly better aided response, speech understanding, and language performance than hearing aid users. There is a negative, moderate correlation between the aided hearing thresholds and treatment-related factors. Conversely, there is a positive, moderate correlation between the word recognition score, revised categories of auditory perception scale, language performance and the treatment-related factors. Conclusions: The aided responses and language development were better among studied cases with cochlear implants and cases with bimodal hearing than cases with hearing aids. Consequently, it is crucial to assess auditory performance and language skills in each child with severe to profound hearing loss individually in terms of hearing aid benefit and the need for cochlear implantation.

This paper proposes a hardware efficient reconfigurable digital hearing aid with minimum delay and minimum matching error, employing Pascal structure based continuously variable bandwidth filter. An FIR filter fitted in between two Pascal structure based sampling rate converters can yield continuous change in bandwidth. The continuously variable bandwidth filter can be employed for audiogram matching with minimal error by proper selection of gain, shift and bandwidth. The proposed design is found to be better than the works in the literature in terms of delay, matching error and hardware complexity. In audiograms with flat region, the modularity property of the Pascal structure can also be utilized to minimize the matching error. The Matching Pursuits Generalized Bit-Planes (MPGBP) algorithm is used to make the reconfigurable filter structure multiplier-less for a power-efficient design. Additionally, the proposed structure is synthesized using FPGA and ASIC technology to support the claimed minimal hardware complexity and power. [ABSTRACT FROM AUTHOR]

Hearing aids (HAs), especially those with sound generators (SGs), are used in the management of tinnitus. However, their comparative efficacies and long-term outcomes remain unknown. Therefore, we investigated the efficacy and long-term outcomes of tinnitus therapy using various HA SG models. We retrospectively reviewed 666 patients with chronic tinnitus characterized by persistent symptoms for >6 months. At the initial visit, the patients received educational counselling on tinnitus (Utsunomiya method) and completed a comprehensive questionnaire comprising the tinnitus handicap inventory, a visual analog scale, the state–trait anxiety inventory, and the emotional intelligence scale. The scores were compared among various models of HA SGs and SGs. The patients underwent follow-ups for up to 2 years. Our results indicated that tinnitus retraining therapy using SGs and conventional HAs effectively managed chronic tinnitus. The prolonged use of HAs appeared to exacerbate tinnitus symptoms, emphasizing the superior long-term effectiveness of SG HAs, particularly ZEN (Widex ZEN, WS Audiology, Lynge, Denmark). Our findings indicate that HAs are useful in the first year, but their prolonged use may exacerbate tinnitus symptoms, whereas HA SGs are effective in the long term. Future studies should account for the variations in tinnitus treatment effects based on the type of sound employed.

Background: Children with hearing impairment have difficulties affecting their ability to understand speech and general communication development. It is essential to understand the background of the factors affecting young children's speech intelligibility in the Pakistani setting. Objective: To explore the factors affecting speech intelligibility among children with hearing impairment. Methods: A total of n=107 individuals were selected for the 6-month study at GMT clinic, Siemens Hearing Clinic, Hearing and Speech Care Clinic, and RHS in Islamabad using non-probability convenience sampling. Children between the ages of 6 and 12 who had mild to profound sensorineural hearing loss and could express themselves at the phrase level met the inclusion criteria. Speech-impairing conditions and progressive or conductive hearing loss were included in the exclusion criteria. Using the Assessing Intelligibility Worksheet, data was collected, in which 17 utterances with 57 words spoken by the therapist participants were repeated and the responses were noted by the therapist. Multiple linear regression, descriptive statistics, and percentage distribution were all analyzed using SPSS 21. Results: A multiple regression model was run to predict intelligibility utterance from age, gender, type of hearing aid, technology of hearing aid, degrees of hearing loss, and talkativeness. This model significantly predicted speech intelligibility of hearing aid users {F (8, 98) = 42.905, p

While targeted rehabilitation can enhance hearing aid self-efficacy (HASE), little research has been done to determine the factors contributing to its predictive value. By investigating the experiences of individuals who successfully use HAs and have high levels of HASE, we hoped to illuminate specific strategies and/or sources of support these individuals share that might explain why high HASE is often linked to successful outcomes. This qualitative study explored the experiences of five older adults who were successful HA users and reported having high HASE. Semi-structured interview guides were developed using the transtheoretical model of behavioral change as a framework. Interviews were analyzed thematically and holistically. Participants attributed their HA success to: intrinsic motivation to improve their hearing, confident self-reliance when making health decisions, willingness to act on advice from trusted others, pro-social personal attributes, positive expectations about HA outcomes, and actively pursuing an optimal HA outcome. For these participants, internal factors related to emotional state and source of motivation, and, to a lesser extent, verbal persuasion played a crucial role in their long-term success. This suggests that external influencers might be less impactful in facilitating success for those with high HASE. [ABSTRACT FROM AUTHOR]

Background: Bone-anchored hearing instruments (BAHIs) are an important alternative solution for hearing loss in a particular group of patients. This study aims to examine shifts in attitudes about BAHIs among hearing health professionals over time. Methods: A survey was designed to assess the knowledge and attitude of otorhinol aryngologists (ENT) and audiologists (Au) concerning BAHIs. The survey was administered in 2019 and 2023 at various conferences. Results: The survey received 243 responses (122 in 2019 and 121 in 2023). Among these, 186 (77%) were from ENTs, while 49 (20%) were from Aus. Notably, the preference for using BAHI for conductive and mixed hearing loss cases increased from 19.3% to 47.9%. The number of individuals with prior experience decreased, yet those who applied BAHIs grew. Signifcant shifts were observed in patient selection based on hearing level, hearing loss type, and clinical condition. The profession and experience emerged as infuential factors in these changes. Conclusion: While most subjects recognized the signifcance of hearing rehabilitation, their fundamental knowledge and familiarity with BAHIs remained limited. A broader implementation of educational and training initiatives focusing on BAHIs is essential to enhance understanding and profciency in this area. [ABSTRACT FROM AUTHOR]

The hearing aid adoption rate among older adults in Japan is lower than that in other developed countries. Herein, a survey was conducted to identify this bottleneck and develop countermeasures. This study aimed to examine whether raising awareness of the relationship between hearing loss and dementia is significant for hearing tests and adopting hearing aids. A questionnaire was administered to participants aged 65 or older who visited a general hospital to determine the background factors (1) for a recent history of hearing tests, (2) for the desire to visit an otolaryngologist and have a hearing test, (3) for recognizing the hearing loss–dementia relationship, and (4) for adopting hearing aids. A total of 517 patients (mean age, 78.06; SD 6.97), representing 2.4% of the region's older-adult population, participated in the survey. A history of hearing tests within five years was significantly associated with recognizing the hearing loss–dementia relationship (adjusted OR 2.36, 95% CI 1.49–3.72). The desire to visit an otolaryngologist or have a hearing test was significantly associated with recognizing the hearing loss–dementia relationship (adjusted OR 1.70, 95% CI 1.02–2.85). Moreover, 39.3% were aware of the hearing loss–dementia relationship. The significant associated factors were being female (OR 2.50, 95% CI 1.64–3.81) and having interpersonal hobbies (OR 1.66, 95% CI 1.11–2.49). The significant background factors for adopting hearing aids were older age (OR 6.95, 95% CI 1.90–25.40), self-reported severe hearing impairment (OR 5.49, 95% CI 2.55–11.80), and living alone (OR 2.63, 95% CI 1.18–5.89). Recognizing the hearing loss–dementia relationship was not a significant factor. Raising awareness of the hearing loss–dementia relationship was not associated with adopting hearing aids for self-reported hearing impairments. However, it may be associated with otolaryngology visits and hearing tests. Thus, steps like hearing screening for older adults are also essential. [ABSTRACT FROM AUTHOR]

Age-related cognitive decline involves a complex set of factors. Among these factors, hearing loss is considered to have a significant impact, but the effect of hearing aid use remains unresolved. The purpose of this study was to evaluate the effects of hearing aid use by simultaneously assessing various factors not only cognitive function but also frailty, anxiety, depression, and quality of life (QOL) in patients with hearing loss. The cross-sectional study at the Hearing Aid (HA) Center was conducted between 2020 and 2021. Initially, associations with cognitive function, QOL, frailty, and mental state among patients with hearing loss were examined, irrespective of whether they wore a hearing aid or not. Next, these patients were divided into HA users (using HA for more than 1 year) and non-users (no prior use of HA) with 42 patients in each group. The average age and 6-frequency pure tone audiometry (PTA) was 74.5 ± 6.5 years and 50.6 ± 12.1 dB, respectively. All participants filled out the questionnaire about their life style, medical condition. Mini-Mental State Examination (MMSE) for cognitive function, Hospital Anxiety and Depression Scale for mental state, Short Form 36 version 2 (SF-36v2) for QOL, and Kihon Checklist for frailty were compared between HA users and non-users and correlated with the auditory data (PTA and speech discrimination). Among 84 patients, 40 had an MMSE score ≦26. All eight scores and three components of SF-36v2 were lower than those of the control group. The patients with hypertension were significantly more in HA user than in non-HA user, whereas there was no difference in diabetes, heart attack, stroke and education. Although HA users were older and showed hypertension more their PTA was worse than that of non-users, MMSE scores were not different between the groups. MMSE scores correlated with both PTA and speech discrimination in non-users but not in HA users. However, a multivariate analysis of the effect of HA use on MMSE scores adjusting for age, hypertension, and hearing loss, could not be revealed. The vitality and mental component summary of the SF-36v2 was better in HA users than in non-users. Elderly patients with hearing loss were cognitively impaired and had low QOL. HA users showed better QOL score than non-HA user, especially about the mental condition. The absence of a correlation between MMSE scores and hearing loss in HA users suggests the potential use of HA in preventing cognitive decline. [ABSTRACT FROM AUTHOR]

To investigate retrospectively the frequency of usage of bimodal stimulation among cochlear implant (CI) users, as well its clinical benefit relative to unilateral use. All subjects had been monitored with the clinical Minimal Outcome Measurements test battery. 103 adults with bilateral postlingual profound sensorineural hearing loss and unilateral CI use were extracted from the local database. These were divided into two groups: those who only used a CI and those who used bimodal stimulation. The preoperative contralateral residual hearing in the bimodal group was significantly better than that of the CI-only group. In both groups, speech perception in quiet and in noise improved after CI, with no significant difference between postoperative unimodal conditions. For the bimodal group, an additional significant improvement was found for the bimodal condition compared to the unimodal. Given the observed auditory benefit of bimodal stimulation in comparison to unimodal stimulation and given the finding that degree of residual hearing is not correlated with bimodal benefits, it is recommended to encourage CI recipients to continue contralateral HA use after CI. As a result of expanding CI criteria worldwide, the population of bimodal users is expected to grow in the near future. [ABSTRACT FROM AUTHOR]

It is unusual to see complications with the preparation of ear mold in order to get hearing aids for children who are in need. However, we came across 2 cases who had a foreign body retained in the middle ear after a long period of time from taking silicon mold impression for hearing aid fitting. One patient presented after 2 years, and the other patient presented after 10 years of hearing aid fitting. We are reporting 2 cases with silicon impression material left in the middle ear for a long period of time after taking an impression for hearing aid fitting and found unexpectedly during exploratory tympanotomy. These reported cases are among the few cases reported worldwide without clear known incidence. This necessitates proper examination by otolaryngologists and the audiologists who are responsible for taking the impression to prevent such complications. [ABSTRACT FROM AUTHOR]

Purpose: The Microphone and Receiver in the ear (M&RIE) hearing aid is designed to consider the pinna cues by placing an additional microphone along with a standard receiver at the entrance of the ear canal. There is a need to clinically validate the technology using speech identification measures, as a literature shortage exists. The objective of the study was to evaluate speech identification and quality rating with hearing aids fitted with standard and M&RIE receivers. Method: Twenty individuals (mean ± SD age being 34.10 ± 11.9 years) with mild-to-moderately severe sensorineural hearing loss were divided into two groups: naïve and experienced. Their speech identification obtained using the receiver in the ear hearing aid compatible with standard and M&RIE receivers were compared. The study assessed speech identification in quiet using ten sentences, calculated SNR-50 using the Spearman–Karber equation, and used an 11-point scale for self-perceived quality rating. Results: The study analyzed data using SPSS and found no significant difference between naive and experienced hearing aid users in quiet and SNR-50 conditions (p > 0.05). However, naive users rated higher in clarity, naturalness, pleasantness, and overall impression of standard receiver settings. Across different receiver settings, both naïve and experienced groups revealed better speech identification with the M&RIE receiver for both SIS (p < 0.05) and SNR-50 (p < 0.05) measures. Conclusion: The study found that placing a third microphone in the ear canal improves speech identification and quality rating in both naïve and experienced users, with pinna and ear canal resonance playing a crucial role in prescribing hearing aid gain.

IntroductionHearing aid (HA) manufacturers have introduced behind-the-ear (BTE) models where the microphone is positioned in the ear canal, which could impact auditory performance by distorting the pinna’s acoustic cues. This study aimed to compare two different BTE HAs with varying microphone positions: the receiver in the ear (RITE) and the transducer in the ear (TIE).MethodsThe study involved 10 participants who had never used HAs before. They used both RITE and TIE HAs bilaterally for 3 weeks. Auditory performance was assessed through free field hearing assessments (hearing thresholds, speech recognition threshold, and speech discrimination score), the Turkish Matrix Sentence Test (TURMatrix), a sound localization test, and the Satisfaction with Amplification in Daily Living (SADL) questionnaire.ResultsThere was no significant difference between TIE and RITE in the free field hearing assessments. However, TIE outperformed RITE in non-adaptive TURMatrix scores in quiet, adaptive TURMatrix scores in noise, and sound localization accuracy at various angles. SADL sub-scores (Positive Effect, Service and Cost, and Personal Image) and overall satisfaction scores were significantly better for TIE.DiscussionThe microphone position in HAs can influence auditory performance. This study demonstrated that TIE provided better speech intelligibility, localization accuracy, and user satisfaction compared to RITE.

IntroductionTo provide better access to hearing aids and lower the devices' costs for patients with mild to moderate hearing loss, the Food and Drug Administration (FDA) changed its rules for hearing aid distribution, making them available to consumers over-the-counter without the supervision, involvement, or prescription of a licensed health care professional. While this regulation provides some patients direct access to hearing aids, the hearing aid fitting creates challenges for the patients and the hearing aid providers. OTC hearing aids should be programmable outside of a clinical setting. This study demonstrates that the self-fitting of hearing aids does not differ significantly from and is non-inferior to the fitting of the device by a licensed audiologist.MethodHearing aid and patient performance after fitting the device by the patient (self-fitting) and a certified audiologist (clinical fitting) were compared in a laboratory setting and a field trial. The laboratory session used a repeated-measures design to assess the reliability and validity of the self-fitting method. A 7–14 days of wear time was used for the field study. The outcome measures for the laboratory session were the differences in acoustical real-ear aided response (REAR). For the wear-time trial, the outcome was the clinical self-report measure of benefit (Abbreviated Profile of Hearing Aid Benefit, APHAB). The benefit of the hearing aid was tested after the self-fitting and the clinical fitting of the hearing aid with a speech-in-noise test (QucikSIN).ResultsThe test outcomes showed no statistically significant differences between repeated self-fitting and clinical fitting of the hearing aids. The hearing aid self-fitting was non-inferior to the clinical fitting.DiscussionIt is important to emphasize that the results and conclusion obtained in this study strictly relate to the specific self-fitting process using the Gaussian Process. Many other potential methods for fitting hearing aids exist and future field studies are required to compare the efficacy of the self-fitting methods.

BACKGROUND: Hearing aids are most commonly used for effective amplification in the hearing impaired. Hearing aid technology has rapidly progressed from analogue to digital sound processing devices. However, controversy still exists in connection with the compression strategy most appropriate for better word and speech recognition especially for the Urdu language. OBJECTIVES: To compare the three amplification strategies, including peak clipping, compression limiting and wide dynamic range compression, to suggest the most appropriate strategy in hearing aids for moderate and severe hearing loss, for the development of better word recognition in the Urdu language. METHODOLOGY: This Quasi-experimental, recruited N=50 children with moderate and severe hearing loss, from Salamat Hospital, Gujranwala from Sept. 2017 to August 2018. The sample of N=50 children included both genders aged 7-15 years, bilaterally fitted with digital programmable, multichannel compression aids, integrating one of three amplification strategies including peak clipping, compression limiting and wide dynamic range compression for at least 1 month in a compensated order across children. After using a specific amplification strategy for at least one week, word recognition score was measured through monosyllabic words in Urdu language. SPSS Ver-20 was used for data analysis. RESULTS: Results revealed significant differences (p=0.000) among word recognition score means of 64.40±5.01, 69.00±5.80 & 94.20±5.75 for peak clipping, compression limiting and wide dynamic range compression hearing aid amplification strategies respectively with maximum increase noted for wide dynamic range compression amplification strategy. CONCLUSION: Wide-dynamic-range compression (WDRC) fitting strategy is better for word recognition in Urdu speaking population than linear amplification, and output compression for moderate and severe hearing loss in children KEY WORDS: Amplification strategies, Compression limiting, Hearing impaired, Hearing aid, Peak Clipping, Wide dynamic Range compression, Word recognition score.
