Purpose: To verify the relationship between consistency in the use of hearing aids, auditory speech perception and vocabulary in children using hearing aids., Methods: The population of Pereira's (2023) study was resumed and the database was analyzed containing information about the Speech Intelligibility Index (SII) for input sounds of 65 dBSPL (with or without hearing aids) of 29 children with neurosensorial hearing loss and hearing aid users bilaterally, with oral language, the number of hours per day of use of the device, four-tone average, results of the repetition of words with or without meaning in 65 dBSPL, Peabody Picture Vocabulary Test - PPVT. The consistency of the use was analyzed through measuring the auditory dosage which takes into account the average of use hours and the audibility with or without the device., Results: The PPVT has a positive correlation with the SII with the device at 65 dBSPL. The four-tone average has a significant negative correlation with the SII in both conditions; and the same happens with the hours on daily usage. The dosage has a significant positive correlation with the SII and negative with the PTA., Conclusion: The receptive vocabulary tends to grow alongside with the audibility dosage increment. Results suggest that listening experience, involving the audibility with or without the device and the consistency of the device daily use must be considered throughout the whole process of the rehabilitation.

Purpose: To verify the effects of cognition on the benefit obtained with the use of hearing aids and on the quality of life of elderly people with hearing loss., Methods: 17 elderly people with moderate sensorineural hearing loss (SNHL) bilateral were evaluated. The elderly people were divided into two groups according to the results of 10-point cognitive screening 10-CS: G1- seven elderly people without change and G2-10 elderly people with a suggestive result of cognitive alteration. Study protocol: self-evaluation questionnaire - (Hearing Handicap Inventory for the Elderly (HHIE)), geriatric depression scale (GDS), quality of life questionnaire - (Short-Form 36 (SF36)) and evaluation of the listening effort through the Visual Analogue Scale (VAS). After the evaluation, the elderly people received hearing aids. After three months of effective amplification, the protocol was reapplied with the inclusion of the International Questionnaire for the Evaluation of Hearing Aids - (IOI-HA)., Results: The sample was characterized according to age, schooling, Critério de Classificação Econômico Brasil Associação Brasileira das Empresas de Pesquisa (ABEP), degree of loss, Índice Percentual de Reconhecimento da Fala (IPRF) and Speech Intelligibility Index (SII) of the ear with better audibility. The statistical study revealed that there was significant difference only in relation to age. The comparative study before and after the intervention revealed a significant improvement in the 10-CS scores in the group G2, in the participation restriction - HHIE, in the listening effort and in some areas of the SF36. There was no difference in QI-AASI between groups second the factor 1, factor 2 and Total Score., Conclusion: There was improvement of the quality of life after three months of amplification use. There was no effect of cognition on the benefit obtained with the use of hearing aids.

Purpose: To establish the relationship between the performance on word recognition tasks, using words with and without sense and degree, and the configuration of hearing loss, by using Speech Inteligibility Index (SII) values as indicators, in children with hearing loss., Methods: SII were established for 55 and 65 Decibel of Sound Pressure Level (dB SPL) input sounds of ten children presenting bilateral sensorineural hearing loss (SNHL), adapted with bilateral hearing aids, and who have oral language as the main mode of communication. The children were submitted to a word and nonsense-word repetition task of two or three intensity degrees. Their productions were analyzed according to the Word Association for Syllable Perception (WASP) Protocol. In the data analysis, the values of SII were compared with the results obtained in each analysis criterion., Results: Pertaining to the words, there was statistically significant difference between the two types of stimuli in 55 dBSPL. As for the performance of consonants and point of articulation, there was a statistically significant difference between stimuli types in 65 and 55 dB SPL, and between intensities 65 and 55 dB SPL in nonsense words., Conclusion: Overall, there was no regularity in the relationship between hearing ability and performance in speech perception tasks. The results suggest that performance in the nonsense words recognition tasks was more related to intelligibility index than to words with meaning, possibly because it limits semantic closure strategies by the subject.

Purpose: Analyze and characterize the oral language of a group of children participating in an auditory rehabilitation program, with at least five years of dispositive use, based on skills of receptive and expressive language measured trough the verbal comprehension RDLS scale., Methods: Transversal and prospective study, evaluating 6 children with age between 8 and 11 years old, all with neurosensory bilateral severe deafness, average time of cochlear implant use of at least 5 years. The evaluation was performed using the RDLS scale, a Brazilian variant of the American scale known as Reynell Developmental Language Scales (RDLS). It consists of the comprehension scale, expression scale, in addition to sub-scales: structure, vocabulary and content., Results: The naming skills were significantly better when compared to abilities involving pragmatic language functions, demonstrated by the sub-scales of content and structure, like the description of a figure and construction of longer sentences or syntactic organization compared to objects, words and figures identification., Conclusion: There were no significant differences between the Comprehension and Expression scales; however, we noted that the performances in more complex structures, like sentences recognition, were inferior to their word recognition performances. These results imply possible implementation of educational and rehabilitation programs for children using cochlear implant.

Purpose: To verify the effect of the multiple exemplar instruction at the acquisition and integration of listening and speaking behaviors, with substantives and substantive-adjective combinations, in children with Auditory Neuropathy Spectrum Disorder (ANSD) and cochlear implant (CI)., Methods: Participants were two children with ANSD that were users of CI. We adopted dictated stimulus and pictures that corresponded to words (substantive) and substantive-adjective syntactic units. The study was arranged in teaching steps that were intercalated with listening and speaking behaviors probes, with all stimuli. The multiple exemplar instruction presented oral imitation (echoic), auditory recognition (listening) and pictures naming (touch) tasks, on a rotating way; the substantives were taught first and, after that, the substantive-adjective combinations., Results: In the pre-test, the participants showed variability and discrepancy in the correct responses percentages of listening and speaking. All achieved firstly 100% correct responses in the listening task and the speaking performances were close to listening after the teaching. All extended substantive learning to substantive-adjective syntactic units., Conclusion: Children with ANSD and CI can learn and integrate listening and speaking behaviors by multiple exemplar instruction, from words to syntactic units.

Purpose: Verify the performance of musical perception and temporal auditory resolution and ordering skills in pre- and post-music therapy patients with cochlear implants (CI)., Methods: Study participants were 11 postlingual CI users with mean age of 47.64 years. All individuals underwent 10 weekly music therapy sessions. Auditory assessment was conducted using the Montreal Battery of Evaluation of Amusia (MBEA) and the Frequency Pattern Test (FPT). All participants were submitted to a placebo condition prior to music therapy and were evaluated at three different times., Results: Significant improvement was observed in the subtests of contour and melody memory after music therapy. No placebo effect or difference in the FPT was observed after music therapy., Conclusion: Music therapy is a useful tool to improve musical skills in adult postlingual users of CI.

Purpose: When children becom cochlear implant users, they have already had the opportunity to develop phonological skills; however, it is possible that they miss sound information during speech and, consequently, present difficulties in competences associated with the learning of reading and writing., Methods: The study sample consisted of 11 normal hearing children aged 7-10 years and a right-ear cochlear implant user enrolled in the 3rd grade of Elementary School. The Cognitive-Linguistic Assessment protocol was used to evaluate the study participants. Data were transcribed and analyzed using descriptive statistics., Results: The following sub-tests presented the highest percentage of children with superior performance: alphabet in sequence (82%), reading of pseudo-words (82%), syllable segmentation (73%), word repetition (82%), copying of shapes (72%), and rapid naming (100%).The cochlear implant user presented superior performance in all the sub-tests except for word repetition, in which average performance was observed. In the rhythm sub-test, none of the normal hearing children presented superior performance, and the cochlear implant user performed poorly., Discussion: It was possible to observe that the condition of being a cochlear implant user is not the only determinant for a child's school failure. There are issues that go beyond auditory integrity, because some normal hearing children performed poorly in sub-tests such as repetition of pseudo-words, rhythm, and alliteration., Conclusion: The cochlear implant user presented a cognitive-linguistic profile very similar to those of his hearing peers.

Purpose: To evaluate the family's perspective of benefits of the frequency modulation (FM) system adapted to children with sensorineural hearing loss., Methods: This is a descriptive, analytical, cross-sectional study with the participation of family members of hearing-impaired children aged 6 to 15 years, users of hearing aids and/or cochlear implants, benefited with the FM system by a hearing health service of the Unified Health System (SUS), Brazil. The FM Listening Evaluation For Children questionnaire with 14 questions was used to evaluate the benefits of using the FM system, the characteristics of the hearing aids and/or cochlear implants, and the brand/model of the FM system the children used., Results: Statistically significant differences were found between the questionnaire responses of FM users and non-users in all situational analyses (quiet, noise, auditory only, distance), with better learning performance and improvements and attention among FM users, from the families' point of view. No method was used to formally evaluate such performances., Conclusion: It was observed that, according to the parents' and guardians' perceptions, the use of FM systems improves the performance of hearing-impaired children in various acoustic situations, with special emphasis on speech recognition in noisy environments and at increased distances from the sound source. Although used in different contexts and situations, the FM system has brought greater benefits for the children in the school environment, according to the respondents.

Purpose: To establish the relationship between speech intelligibility index (SII) values generated at the verification of hearing aids programmed according to DSLm [i/o] v5 prescription rule and a proposed individual classification that considers the combination of hearing loss degree and configuration., Methods: Forty-one children aged between 4 and 80 months were selected, totaling 78 ears for analysis. We considered hearing thresholds at the frequencies of 250, 500, 1000, 2000 and 4000 Hz; and analyzed values of the Speech Intelligibility Index (SII) for the input signal of 65 dB SPL obtained during the verification of hearing aids using the equipment Verifit®Audioscan., Results: Hearing losses were classified into five homogeneous groups regarding audiometric degree and configuration. The groups were heterogeneous when compared to each other. From the groups, three ranges of SII values were determined. Equations were developed for classification of hearing loss according to groups and for determination of the adjusted SII values., Conclusion: The SII value is a useful indicator of audibility for speech sounds in different characteristics of hearing losses, and can guide observations of auditory skills. The SII has stronger relationship with the association of the audiometric degree and configuration when compared with degree of hearing loss alone.

Purpose: To verify the effect of the use of auditory prostheses on speech perception tests in elderly individuals with and without tinnitus having hearing impairment., Methods: We evaluated 24 elderly patients with moderate sensorineural hearing loss, aged between 60 and 70 years, distributed into two groups according to the presence or absence of tinnitus. All of them were fitted with micro-canal auditory prostheses from the same manufacturer and model, and underwent speech perception tests. The assessments were performed with and without the amplification devices after 1 and 3 months of effective use. For data analysis, Mann-Whitney test was used., Results: Elderly people from the tinnitus group presented lower performance in speech perception tests than those from the group without tinnitus. In the evaluations with the devices, the performance of both groups was better than when they were evaluated without hearing aids., Conclusion: The acoustic stimulation through the effective use of hearing aids produced better speech perception, regardless of the presence of tinnitus.

Purpose: This review aimed at presenting the benefits regarding the speech perception in noise shown by children who wear hearing aid devices and/or cochlear implants with the Frequency Modulation (FM) System at school., Research Strategy: A bibliographic survey was conducted in an electronic database with standardized search until the year 2012, and a manual search was performed by using specific keywords., Selection Criteria: For the selection and evaluation of the scientific studies chosen in the search, criteria were established covering the following aspects: type of study, participants, adopted intervention, and evaluation of results., Data Analysis: The FM system was verified to improve speech perception and speech threshold in noise in all studies., Results: Regarding the performance as to type, the best results were obtained when children used the personal FM system, followed by the table and the sound field systems., Conclusion: After extensive review of national and international literature, it was concluded that the studies indicate the need for further research concerning mainly the impact of the FM system on the school performance of children who have sensory devices coupled to the FM system. Findings in the literature with relation to the publications focused on speech perception in noise did not relate educational and auditory aspects.

Purpose: To verify the effect of long-term use of hearing aids with frequency compression for verbal behavior tests and daily activities., Methods: Thirty-two adults, aged between 30 and 60 years old, with moderate to severe sensorineural hearing loss at high frequencies with steeply sloping configuration were divided into two groups: 16 with hearing aids with frequency compression algorithm enabled and 16 not enabled. All participants underwent the detection tests of consonant sounds, monosyllable recognition in quiet environments, identification of fricative monosyllables, and Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire in five times throughout a 12-month trial., Results: Detection of consonant sounds, recognition of monosyllables in quiet environments and identification of fricative monosyllables improved significantly with frequency compression enabled. Participants had their APHAB scores improved whether they were adapted to the frequency compression or not., Conclusion: Frequency compression provides the anticipated improvement in audibility, detection of high-frequency consonant sounds, and recognition of monosyllables.

Purpose: This study aimed at analyzing the association between the lexical development of children with hearing impairment and their psychosocial and socioeconomic characteristics and medical history., Methods: An analytic transversal study was conducted in an Auditive Health Attention Service. One hundred and ten children from 6 to 10 years old using hearing aids and presenting hearing loss that ranged from light to deep levels were evaluated. All children were subjected to oral, written language and auditory perception tests. Parents answered a structured questionnaire to collect data from their medical history and socioeconomic status, and questionnaires about the features of the family environment and psychosocial characteristics. Multivariate analysis was performed by logistic regression, being the initial model composed by variables with p<0,20 in the univariate analysis. In the final model, we adopted a significance level of 5%., Results: The final model of the multivariate analysis showed an association between the performance on the vocabulary test and the results of phonemic discrimination test (OR=0.81; 95%CI 0.73-0.89)., Conclusion: The results show the importance of stimulating the auditory processing, particularly the phonemic discrimination skill, throughout the rehabilitation process of children with hearing impairment. This stimulation can enhance lexical development and minimize the metalanguage and learning difficulties often observed in these children.

Introduction: Evaluation of cortical auditory evoked potentials in children with cochlear implants has been proven to be an effective method for assessing cortical maturation after electrical stimulation., Objective: To analyze the changes in latency values of cortical auditory evoked potentials before and three months after cochlear implant use., Material and Methods: This was a case-control study with a group of five children using cochlear implant awaiting activation of the electrodes, and a control group composed of five normal-hearing children. Auditory electrophysiological assessment was performed by the testing of the cortical auditory evoked potentials at two different periods: prior to cochlear implant activation and after three months of cochlear implant use., Results: A significant decrease in the latency time of the P1 component was observed after three months of stimulation via cochlear implant, whose values were higher than those from the control group. The younger the child was at electrode activation, the greater the reduction in latency of the P1 component., Conclusion: Changes in the characteristics of cortical auditory evoked potentials can be observed in children who receive cochlear implants; these changes are related to the age of intervention, suggesting a rapid maturation of the auditory pathways after electrical stimulation.

Unlabelled: Studies have shown that elderly people with cognitive impairments benefit more from hearing aids with slower recovery times., Objective: To study participation constraints and speech recognition in noise of elderly subjects equipped with hearing aids of different recovery times according to cognitive impairment status., Method: Fifty subjects aged between 60 and 80 years were followed for four months. They were divided at first in groups of individuals without (G1; n = 24) and with (G2; n = 26) cognitive impairment based on results of the Alzheimer's Disease Assessment Scale -Cognitive Sub-scale test. Half the members of each group received hearing aids with faster recovery times and half got slower recovery aids, thus forming four groups: two without cognitive impairment (faster recovery - G1F; slower recovery - G1S) and two suspected for cognitive impairment (faster recovery - G2F; slower recovery - G2S). All subjects were interviewed, submitted to basic audiological assessment, asked to answer the Hearing Handicap Inventory for the Elderly questionnaire, and tested for speech recognition in noise. ANOVA, McNemar's test, and the Chi-square test were applied. The significance level was set at 5%., Results: There was significant improvement in participation constraint and speech recognition in noise with hearing aids alone. Sub-group G2F needed more favorable signal-to-noise ratios to recognize 50% of the speech in noise., Conclusion: Participation constraint and speech recognition in noise were improved regardless of recovery times or cognitive impairment status.

Objective: To evaluate telephone speech perception in individuals who received cochlear implant in the period 1993-2003., Methods: Twenty seven CI users were divided into pre and post-lingual groups, being the speech perception assessed in two stages: first by a list of sentences imposed on speakerphone with the same mapping used to evaluate the phone and, in a second stage, using the landline, landline phone adapter with CI and cell phone., Results: In the group of pre-lingual hearing loss, 75% of subjects were able to maintain a dialogue with the interlocutor and 19% did so with difficulty. In the post-lingual group, 89% were able to maintain the dialogue with the interlocutor and 11% did so with difficulty. Both groups of subjects pre and post-lingual use the phone as a media, and most have satisfactory performance without the need for aid or CI accessories., Conclusion: One of the benefits of the CI is to introduce the life of the hearing impaired phone use regardless of their technology and accessories, as well as with the phone adapter and cell phone. In this study, most individuals CI users showed satisfactory performance in the comprehension of sentence and questions by the telephone, with better performance, although discrete, for the group post-lingual. Thus, there is the importance of careful indication of the IC and auditory rehabilitation program that minimize the impact of deafness in the communication, especially via telephone, regardless of the time when the hearing was acquired. So, this fact improves the conditions for CI users to maintain their daily activities, following the dynamism of contemporary life.

Purpose: To verify the effects of auditory rehabilitation through the analysis of quantitative and qualitative aspects of the Staggered Spondaic Word Test (SSW) in elderly people who have recently started wearing hearing aids., Methods: The study included 17 elderly people, who have recently started wearing hearing aids, aged between 60 and 84 years old, divided into two groups: G1, for those who only wore hearing aids, and G2, for those submitted to an auditory rehabilitation program structured in seven sessions, including auditory counseling and training. All subjects were evaluated with the SSW test at two different moments, the beginning and the end of the study. All data were statistically analyzed., Results: Regarding quantitative aspects, subjects in G1 showed improvements, but no statistically significant differences were observed between evaluations, while G2 presented statistically significant improvements on the competitive right, the non-competitive left and the total number of hits. When comparing the final performance of both groups, there were statistically significant differences concerning almost all of the variables with greater results to the G2 group. Regarding qualitative aspects, volunteers in both groups had difficulties with phonemic decoding, gradual memory loss, organization and integration in both assessments, with different alterations between them., Conclusion: The scores obtained by subjects in G2 submitted to the hearing rehabilitation in the variables competitive right and left non-competitive show especially the improvement on the left hemisphere, due to auditory training. For further evidence of differences between the results of qualitative aspects, a longer period of time would possibly be required in order for changes in auditory perception to occur associated with other sensory functions.

Purpose: To assess the characteristics of P1 component in children presented with pre-lingual hearing loss, users of cochlear implants, and correlate them with speech perception performance., Methods: Ten children presented with pre-lingual sensory neural hearing loss using cochlear implants participated in this research. The cortical auditory evoked potential research was carried out with the /da/ speech stimulus, presented in free field, in three moments: at cochlear implant activation, with three and six months following activation. The Infant-Toddler Meaningful Auditory Integration Scale was used to verify the speech perception., Results: The correlation of the three moments of the test with the latency and the amplitude of P1 component through analysis of variance were observed. The comparison of latency and amplitude of P1 in each assessment moment was performed with Tukey's test. Wilcoxon and t-test showed that the score on the Infant-Toddler Meaningful Auditory Integration Scale increased significantly with the time of cochlear implant use, nevertheless with no correlation with the latency and amplitude of P1 component in the moments assessed, as demonstrated by Spearman's and Pearson's correlations., Conclusion: The latency and amplitude of P1 component diminish as the time of cochlear implant use increases. However, there was no correlation between its development and speech perception performance.

Purpose: To establish a profile of the patients treated in a Hearing Aids Grant Program of the Brazilian Ministry of Health, by analyzing the variables: age, sex, type and degree of hearing loss, number of aided patients, adaptation type (unilateral or bilateral), and adapted ear., Methods: This is a descriptive observational study, retrospective in a cross-sectional perspective, which included patients treated between February 2006 and July 2010, totaling 1,572 individuals;, Results: Their ages ranged from 3 to 100 years, mostly elderly (52.8%), with no frequency difference between the sexes. The sensorineural (73.12%) and moderate (54.7%) hearing losses were the most frequent ones, except in children, in whom the degree found was more profound (45.3%). More than 99% of the patients were aided, 258 unilaterally and 1,302 bilaterally., Conclusion: Mostly patients presents 60 years old or more, with no frequency difference between the sexes. The sensorioneural and moderate hearing losses were the most frequent ones, except in children. More than 99% of the patients were aided and the conducts were defined based in the audiological diagnosis and patient's needs.

Unlabelled: Aging can alter temporal processing and affect speech perception., Aim: To compare temporal processing auditory processing in elderly subject to and new hearing aid users., Materials and Methods: The study included 60 elderly patients with bilateral sensorineural hearing loss. The procedures selected were the Duration Pattern Tests (DPT) and gaps in noise (GIN) test were used to analyze the responses of correct identification, and the temporal acuity threshold before and after the fitting of hearing aids., Study Design: clinical and experimental research with non-probability sample of convenience., Results: There was no statistically significant difference between the responses from GI and GII individuals. The elderly users of hearing aids had a lower gap detection threshold, greater recognition of gaps and of discrimination of the duration pattern in relation to when they were only potential users., Conclusion: There was a deterioration in temporal processing skills, regardless of hearing loss degrees. Thus, the effect of acoustic stimulation by the use of a hearing aid improved resolution and temporal ordering.

Unlabelled: The technological advances in cochlear implants and processing strategies have enabled subjects affected by severe to profound hearing loss to hear sounds and recognize speech in various different degrees. The variability of hearing outcomes in subjects with post-lingual deafness has been significant and cochlear implant indications have been extended to include an ever larger population., Objective: This paper aims to look into the groups of post-lingual deafness patients to find where cochlear implants have yielded better outcomes than conventional hearing aids., Materials and Methods: Review the literature available on databases SciELO, Cochrane, MEDLINE, and LILACS-BIREME. The publications selected for review were rated as A or B on evidence strength on the day of the review. Their authors analyzed and compared hearing aids and cochlear implants in populations of post-lingually deaf patients., Study Design: Systematic review., Results: Eleven out of the 2,169 papers searched were found to be pertinent to the topic and were rated B for evidence strength. Six studies were prospective cohort trials, four were cross-sectional studies and one was a clinical trial., Conclusion: The assessment done on the benefits yielded by post-lingually deaf subjects from cochlear implants showed that they are effective and provide for better results than conventional hearing aids.

Unlabelled: A new era has arrived in auditory rehabilitation with the introduction of new technologies such as electroacoustic stimulation (EAS). EAS is indicated for patients with residual hearing at low frequencies and severe or profound hearing loss at high frequencies. These patients have no indication for conventional cochlear implant and have difficulties in adapting to individual sound amplification devices. Preservation of hearing is vital in this process; the surgical technique must be based on this concept., Objectives: To present the cochlear implant surgical technique with MED-EL Mand FlexEAS to preserve hearing in patients with hearing loss at high frequencies and to maintain low frequency hearing. We are the first institution to carry out this treatment in Brazil., Methods: A case report of the surgical technique carried out in four patients; the procedure was carried out by the cochlear implant group of a specialized clinical hospital., Results: The procedures were successful and uneventful., Conclusion: We described the technique used at our institution for implants using EAS; the surgical technique is complex and includes steps for preservation of hearing.

Purpose: To establish relationships between age at onset of individual hearing aid use, functional hearing, communication skills, family involvement and family expectations regarding language development of children diagnosed with hearing loss during the first three years of life., Methods: Thirty-five babies diagnosed with moderate to severe hearing loss who were receiving treatment at the Children's Hearing Center/Derdic (CeAC) were evaluated during a period of 24 months. Assessments were carried out every six months and included: VRA--Visual reinforcement audiometry (with and without amplification); IT-MAIS; MUSS; and satisfaction of family regarding child development., Results: Cluster analysis was performed among the subjects. Consistent use of hearing aids was the only variable that exhibited a strong relationship with hearing and language skills. Children whose parents were not satisfied exhibited severe hearing loss and limited auditory capacity even with the use of hearing aid, and, consequently, poor auditory skills and speech production., Conclusion: Datalogging monitoring can guide the knowledge of speech-language pathologists and audiologists and it can also be used on strategic planning. Family involvement, quality of parental participation in the intervention program as well as expectations about the future are also important aspects to consider as these can aid therapists and researchers on the assessment of deaf babies intervention effectiveness.

The cochlear implant (CI) represents the most important advance in the treatment of individuals with severe to profound bilateral hearing loss who do not benefit from hearing aids. Children who receive the CI during the critical period of neuroplasticity of the auditory system, when combined with speech therapy, have the chance to develop the auditory and linguistic skills similarly to their normal hearing peers. Two cases of implanted children are presented in this study, and one of them was not enrolled in a formal aurioral therapeutic program since the implantation surgery. At the moment of language and auditory assessment, the children were 2 years and 5 months old, and the CI had been used for 11 months. According to the results presented, it was observed that the child enrolled in rehabilitation program had better auditory and language performance when compared to the other child. Despite the remarkable benefits that the CI provides to children with hearing impairment, the device itself only provides the child with the audibility of environmental sounds and speech signal. For the auditory and language development to happen, it is necessary, among other factors, a speech-language intervention, with partnership between professionals and parents.

Purpose: To analyze the effects of an auditory rehabilitation program for the temporal ordering ability, of duration and pitch patterns of sounds, in elderly hearing aids users., Methods: Participants were 17 elderly people, with ages between 60 and 84 years, divided into Control Group (CG), which only used hearing aids, and Study Group (SG), which were submitted to an auditory rehabilitation program that included auditory counseling and training. All subjects were assessed at the beginning and at the end of the study, through the Duration Pattern Sequence and Pitch Pattern Sequence tests. The period between assessments was seven weeks., Results: In the Duration Pattern Sequence test, CG subjects showed mean values of accuracy in the murmured condition of 48.64 and 54.43%, for initial and final assessments, respectively; SG subjects, presented 60.39 and 76.28%. In the named condition, CG presented 51.93 and 52.43%, and SG, 63.94 and 77.44% for initial and final assessments, respectively. In the Pitch Pattern Sequence test, CG subjects showed mean values of accuracy in the murmured condition of 80.62 and 79.94%, and SG subjects, of 79.78 and 90.39%, for initial and final assessments, respectively. In the named the condition, CG presented 82.64 and 84.21%, and SG, 82.94 and 85.89%, for initial and final assessments. There was a difference only for SG subjects in the murmured and named conditions of the Duration Pattern Sequence test, in the named condition of the Pitch Pattern Sequence test, indicating higher mean values in the final assessment., Conclusion: The auditory rehabilitation program to elderly hearing aid users provide satisfactory improvement in recognition, temporal ordering, and naming of duration and pitch patterns of sounds.

Purpose: To establish the frequency of genetic mutations related to sensorineural hearing loss (SNHL); to verify if there is association between the degree of SNHL and the presence of genetic alteration; and to verify if the Minimal Response Levels (MRL) with hearing aids vary according to the genetic alteration., Methods: Thirty hearing aids users with ages between 8 and 111 months were evaluated. The evaluation procedures used were: pure-tone audiometry; the auditory steady state response (ASSR) on sound field, with and without hearing aids; and genetic study of the hearing loss., Results: Three genetic mutations were diagnosed: 35delG, A1555G and A827G, and the children with these mutations showed higher degree of SNHL. There was no difference between the genetic patterns regarding the degree of SNHL, except for patients with A827G mitochondrial mutation, because all subjects with this mutation had profound SNHL. The difference between the MRL obtained with and without amplification, considering the presence of mutation and the degree of SNHL, was higher in children with moderate SNHL without genetic alterations, both in behavioral and electrophysiological evaluations., Conclusion: Genetic mutations were found in 36.7% of the sample, justifying the importance of genetic tracking in the hearing habilitation process. Children with genetic mutations showed higher degrees of hearing loss. The different mutation patterns do not directly determine the degree of hearing loss. The best thresholds with amplification were found in children with moderate hearing loss without genetic alterations.

Unlabelled: According to the IBGE, Brazil had 21 million elderly persons in 2008., Objective: To study the effects of speech therapy - fitting of hearing aids - on the quality of life of elderly persons and restriction of participation according to sex and age., Material and Method: 50 elderly subjects, 23 females and 27 males, were allocated to Group 1 and Group 2, and were assessed with questionnaires (HHIE and SF 36) before and one year after fitting hearing aids; subjects were monitored every two months., Results: The HHIE Social and Emotional Scale was significant with regards to sex and age after fitting hearing aids. The SF 36 results after fitting hearing aids were significant in six of eight test aspects. Two test aspects were not significant after fitting hearing aids; pain, however, was significant in the elderly group 2., Conclusion: There is little awareness of participation restrictions after the HHIE intervention. There is improvement in quality of life after rehabilitation. Retrospective study.

Unlabelled: The development of hearing aid (HA) software programming does not replace the analysis of real ears with probe microphones., Aim: To compare simulated insertion gain in HA software programming and real ear insertion gain., Method: A prospective study of 62 patients (aged from 29 to 93 years; 30 male and 32 female). All patients presented unilateral (n=14) or bilateral (n=48) and mild to profound sensorineural hearing impairment. 110 ears assessed. Data was gathered from medical records and the insertion gain was obtained in real ears for comparison with the simulated insertion gain in HA software programming. Statistical tests were applied to analyze the correlation of data - difference of real ear and simulated insertion gain., Results: HA software programming simulated insertion gain was higher than real ear insertion gain obtained with probe microphone measures. There were statistically significant frequency differences. Age did not correlate with the difference of real ear and simulated measures., Conclusion: The use of real ear measures is important during verification of HA.

Purpose: To compare the Percentage of Consonants Correct (PCC) index of children with and without hearing loss, and to verify whether the time using hearing aids, the time in therapy, and the time spent until hearing loss was diagnosed influence the performance of deaf children., Methods: Participants were 30 children, 15 with hearing impairment and 15 with normal hearing, paired by gender and age. The PCC index was calculated in three different tasks: picture naming, imitation and spontaneous speech. The phonology tasks of the ABFW - Teste de Linguagem Infantil were used in the evaluation., Results: Differences were found between groups in all tasks, and normally hearing children had better results. PCC indexes presented by children with hearing loss characterized a moderately severe phonological disorder. Children enrolled in therapy for a longer period had better PCC indexes, and the longer they had been using hearing aids, the better their performances on the imitation task., Conclusion: Children with hearing loss have lower PCC indexes when compared to normally hearing children. The average performance and imitation are influenced by time in therapy and time using hearing aids.

Background: After the adaptation of hearing aids, an improvement in speech understanding is expected to occur, called acclimatization., Aim: To determine the effect of acclimatization in sentences recognition threshold, for the conditions of silence (SRTQ) and noise (SRTN), in new users of hearing aids, evaluated prior to and after acclimatization, without the use of the hearing aids., Method: Participants were 40 individuals, aged between 28 and 78 years, with mild to moderate sensorineural hearing loss. Tests were conducted in three sessions: prior to the adaptation of the hearing aids, fourteen days and three months later.The Portuguese Sentences Lists test in free field was used for testing, and the SRTQ and SRTN were obtained (with noise level settled at 65 dB A). Results were expressed through the signal/noise ratios., Results: The mean values for the SRTQ in the 1st, 2nd and 3rd sessions were 54.43, 51.71 and 52.22 dB A respectively,. The mean signal/noise ratios for the 1st, 2nd and 3rd sessions were 1.67, 0.30 and -0.03 dB A. When comparing the results obtained between the testing sessions, a statistically significant difference was observed between the 1st and 2nd sessions, and between the 1st and 3rd sessions for the values obtained in the testing conditions of silence and noise., Conclusion: There was a progressive reduction of sentences recognition thresholds and signal/noise ratios indicating an improvement in performance even when assessing the individuals without the hearing aids. This improvement can be related to the effect of acclimatization.

Unlabelled: The use of hearing aids can provide plasticity to the hearing system as well as improve speech recognition as time goes by., Aim: To compare the influence of the length of hearing aid use on the benefit obtained with the hearing aids in adults and the elderly, new hearing aids users., Materials and Methods: Prospective study with 40 individuals with mild to moderate-severe sensorineural hearing loss, gathered in 2 groups: Adults Group--13 people aged between 28 and 59 years old; and Elderly Group--27 people aged between 61 and 78 years old. These people were assessed 14 and 90 days after hearing aid fitting. Sentence recognition threshold in silence and under noise as well as the percentage indexes of sentences recognition in silence and under noise were obtained., Results: The comparison between values obtained after 14 and 90 days of hearing aid use did not show statistically significant differences. When comparing values between the groups, no statistically significant difference was observed either., Conclusion: We did not find influences of the length of hearing aid use and the benefit obtained from using them; the results achieved by adults and the elderly were similar.

Background: benefit and acclimatization., Aim: to characterize the short-term benefits presented by adults, recent users of hearing aids, through objective (functional gain) and subjective (self-evaluation questionnaires) procedures. The possible occurrence of the phenomenon of acclimatization was also investigated based on the analysis of the speech recognition percent index (SRPI) before the fitting of the hearing aids and after four and 16/18 weeks of hearing aids use., Method: sixteen subjects, with ages between 17 and 89 years, with symmetric moderate or severe sensorineural hearing loss, recent hearing aid users, were evaluated. The study was divided in three phases: before the hearing aids fitting, and after four and 16/18 weeks following the fitting process. In all of the phases the following procedures were used: pure tone audiometry, speech recognition percent index, speech recognition threshold and the Hearing Handicap Inventory for Elderly Screening Version or the Hearing Handicap Inventory for the Adults Screening Version, and the Abbreviated Profile of Hearing Aid Benefit. After the hearing aid fitting process, subjects were submitted to free field audiometry., Results: results showed statistically significant differences between objective and subjective measures after the use of hearing aids, indicating short-term benefit. However, as time went by, the benefit obtained with the use of hearing aids did not improve significantly, suggesting that benefit does not increase with time. SRPI as well as subjective measures improved with long-term hearing aid use, but such differences were not statistically significant., Conclusions: short-term benefits were obtained with the use of hearing aids, however the phenomenon of acclimatization was not observed through the SRPI.

Background: Sensorineural hearing impaired individuals benefit themselves with the use of nonlinear amplification, once the compression tries to reestablish the sensation of normal loudness. However, the literature is still controversial in relation to the benefits for speech recognition in users of linear and nonlinear hearing aids., Aim: For this reason, the purpose of this study was to compare the performance of linear and nonlinear hearing aid users through objective and subjective evaluations, verifying the best circuit for hearing adaptation and speech recognition in silence and in noise., Method: 21 bilateral hearing aid users, who had been using the hearing aid for at least 3 months, with 12 to 64 years of age and with mild to moderate-severe hearing losses were studied according to the type of amplification used, forming two groups: linear group composed by 10 linear hearing aid users; and nonlinear group, composed by 11 nonlinear hearing aid users. Speech recognition tests were applied in silence and in noise, as well as the International Outcome Inventory of Hearing Aids questionnaire., Results: Statistically significant differences were not observed between the groups for the speech recognition tests, in silence and in noise, and for the questionnaire., Conclusion: It can be concluded that no difference exists in the performance of linear and nonlinear hearing aids users, regarding the objective evaluations (speech tests) and the subjective evaluations (questionnaire), that indicate a better adaptation or a better speech recognition in silence or in noise.

Background: assessment of the subjective benefit brought by the use of the hearing aid., Aim: to determine the benefit brought by the use of the hearing aid through a subjective procedure., Method: the subjective benefit of the hearing aid was assessed in 15 hearing impaired individuals, novice hearing aid users, through the Abbreviated Profile of Hearing Aind Benefit (APHAB) self-assessment questionnaire, which was answered before and after the hearing aid fitting., Results: the results demonstrated statistically significant differences between the conditions with and without the hearing aid, indicating a better performance with the use of amplification., Conclusion: this procedure demonstrated to be valuable for the assessment of the benefits brought by the process of hearing aid fitting.
