Purpose: Specific learning disorder (SLD) refers to a pattern of learning difficulties characterized by problems with reading, writing, or mathematics that are not solely due to intellectual disabilities, sensory deficits, or other neurological or medical conditions. It is a neurodevelopmental disorder that affects the processing and organizing of information. Auditory and cognitive processing is affected in most children with SLD, although to a varying degree. However, it is still unclear whether there exists any relationship between auditory and cognitive processing disorders in children with SLD. Method: We tested 1,259 children, of whom 77 were diagnosed as SLD and 30 age- and gender-matched typically developing (TD) children were selected. Auditory processing abilities were assessed for auditory discrimination, pattern perception, closure, temporal processing, binaural integration, and separation using standardized tests and procedures. Cognitive processing was measured using working memory, short-term memory, and attention tasks. Results: The test data of the TD children were taken as the norm. Based on the normative range, children with SLD were divided into those with auditory processing disorder (APD; n = 31) and those without APD (n = 46). A regression model highlighted a robust positive relationship between APD and cognitive processing, particularly pronounced in SLD with APD children. The results are discussed, supporting the information-processing theory of learning disability and highlighting a complex loop between auditory and cognitive deficits in children with SLD. Conclusions: The findings underscore the critical role of both auditory and cognitive abilities in children with SLD. Tailoring the intervention to break the loop is recommended, which may improve learning abilities more effectively. [ABSTRACT FROM AUTHOR]

Children with speech sound disorder (SSD) have incomplete phonological acquisition without organic alteration. These children's speech exhibits multiple phoneme omission, substitution, and distortion errors. Auditory processing disorders (APD) are associated with speech sound disorders. Since APD prevents the development of a stable representation of phonemes in the brain, it may cause speech issues and make semantics, syntax, and phonology challenging to acquire. The review summarises behavioral findings of auditory processing abilities in children with SSD. The study used a literature search of electronic databases (Google Scholar, Science Direct, Research Gate, PubMed) from 2007 to 2022. The retrieved articles were assessed in two stages: title and abstract screening, followed by a full-length article review. Six articles were selected after the full-length review of 12 shortlisted articles. The review of the articles showed that temporal processing abilities are affected in children with SSD. Thus, temporal processing is critical for developing phonological awareness because it is vital for perceiving and rapidly changing acoustic cues in speech. The close relationship between temporal processing and phonological awareness in children with SSD highlights the importance of including temporal processing assessment in these children. Appropriate auditory training which taps into temporal processing skills may improve phonological awareness in these children. The effect of auditory processing training on phonological skills in SSD children needs further study. [ABSTRACT FROM AUTHOR]

Background and Aim: Psychoacoustics includes studying the perceived effects of changes in sound intensity, temporal, and frequency aspects that are critical for speech perception. Psycon is one such software used in studies to assess psychoacoustic abilities. Psycon has the potential for wide clinical applications in psychoacoustic research and relies on Auditory syntaX (AUX), a program designed specifically to handle auditory signals. The current study aimed to determine the test-retest reliability of the Psycon application for differential sensitivity measures of frequency, intensity, duration and silence. Methods: The study included 39 participants with normal hearing sensitivity. Psychoacoustic measures, namely, gap detection threshold, duration discrimination threshold, difference limen of intensity, and difference limen of frequency, were used to assess test-retest reliability. The test-retest reliability of all measures was checked in two separate sessions within one day. Results: The reliability of each measure was measured using Cronbach's alpha. Test-retest reliability of various psychoacoustic tests measured with Psycon ranges from good to excellent. difference limen of frequency had the highest reliability, followed by duration discrimination thresholds, difference limen of intensity, and gap detection thresholds. Conclusion: Psycon appears to be a reliable tool for assessing different psychoacoustic abilities. [ABSTRACT FROM AUTHOR]

Purpose: The present systematic review aims to understand auditory processing abilities in children with nonsyndromic cleft lip and/or palate (NSCL/P). The review summarizes questionnaire, behavioral, and electrophysiological findings of auditory processing abilities in children with NSCL/P. Method: The study used a literature search of electronic databases (e.g., Pub Med, Google Scholar, J Stage, Research Gate, ScienceDirect) and the AIISH repository from 2000 to 2021. The retrieved articles were assessed in two stages: title and abstract screening, followed by a full-length article review. About 13 articles were selected after the full-length review of 17 shortlisted articles. All selected studies used cohort design. Result: The review showed that speech perception in noise and temporal processing were the majorly affected processing abilities in children with NSCL/P. The review also showed that cleft palate children are more prone to auditory processing deficits than other cleft subgroups. These auditory processing deficits in NSCL/P children may cause delayed speech and language skills, reading, and learning disabilities, which are highly reported in these children. Conclusion: Auditory processing evaluation should be a part of the audiological test battery for these children to promote early diagnosis and management. [ABSTRACT FROM AUTHOR]

The study aimed to assess the risk of hearing loss in full-term neonates with hyperbilirubinemia, examining the relationship between bilirubin levels, onset age of hyperbilirubinemia, and hearing impairment. Additionally, it investigated whether hearing loss was transient or late-onset, using a cost-effective double-screening method.The study included 160 full-term neonates aged 0-1 month. Following completion of phototherapy for hyperbilirubinemia, all infants underwent initial screening with otoacoustic emissions (OAEs) and automated auditory brainstem responses (AABR). A second screening was administered to all infants within one month. Infants referred during the second screening, regardless of their first screening results, underwent diagnostic evaluation. For analysis, the infants were categorised into 4 groups, based on their bilirubin levels and onset of jaundice.After the initial screening, 37% of infants were referred, which decreased to 9% after subsequent screening, suggesting transient hearing loss in 76% of initially referred infants. Permanent hearing impairment was confirmed in 2.5% of infants following diagnostic evaluation, with 3 infants diagnosed with ANSD and 1 infant with sensorineural hearing loss, all from categories characterized by elevated bilirubin levels. The findings indicated that even bilirubin levels as low as 12 to 15 mg/dl could lead to hearing loss, particularly when jaundice onset occurred early.This study highlights the effectiveness of double-screening for identifying transient hearing losses in infants with hyperbilirubinemia, minimizing the need for diagnostic referrals. It underscores the importance of considering both bilirubin levels and onset timing to assess auditory risk fully. [ABSTRACT FROM AUTHOR]

Introduction: The current study aimed to evaluate the olivocochlear bundle functioning and speech perception in the presence of noise in females with Polycystic ovary syndrome (PCOS). Method: Twenty participants in the age range of 18-25 years were included in the study. They were equally divided into two groups: group 1 included females diagnosed with PCOS, and group 2 included healthy adult male participants. Medial olivocochlear (MOC) functioning was evaluated using contralateral suppression of transient otoacoustic emissions (TEOAE). In addition, speech perception in noise was assessed using a quick speech perception in noise test in Malayalam. Results: Results showed a significant difference for the TEOAE amplitude and signal to noise ratio (SNR) of TEOAEs in quiet and in the presence of contralateral noise and the speech perception in noise between the two groups. Also, no contralateral suppression was noted in the clinical group suggesting that MOC functioning is affected in individuals with PCOS. Conclusion: It can be concluded that medial olivocochlear bundle functioning and speech perception in noise is affected in individuals with PCOS, which can be attributed to the abnormality in the hormonal status of PCOS.
