“…In case of multiple handicaps, BERA is the only test which can give accurate picture of hearing sensitivity. 12 In case of high risk babies who are exposed to multiple risk factors like preterm babies, neonatal jaundice, neonatal convulsions, birth asphyxia & LBW & even other multiple risk factors which have chances of impairing hearing ability, BERA should be carried out as a routine procedure to detect the hearing loss in such babies. In present study bilateral severe hearing loss was present in 76 cases (72.4%).…”

Background: Brainstem evoked response audiometry (BERA) is a non-invasive diagnostic tool which can be used to assess the early hearing loss. The objectives of the study were to find out the risk factors for severe hearing loss in children and to evaluate the role of BERA in early diagnosis of severe hearing loss in children.Methods: The present hospital based cross sectional study was conducted on 105 children suffering from severe hearing loss. Risk factors of hearing loss was assessed in these children and brainstem evoked response audiometry was performed. Results: Out of 105 children studied risk factors for hearing loss were present in 69 cases (65.71%) in which several cases had multiple risk factors. History of prolonged stay at NICU was present in 23 cases (21.9%). 11 (10.5%) cases had suffered from meningitis while history of cerebral malaria was present in 2 cases (1.9%). History of cerebral palsy was present in 5.7% cases. The family history of hearing loss was present in 15 patients (14.3%). Bilateral severe hearing loss was present in 76 cases (72.4%) while in 13 cases (12.4%) there was bilateral severe to profound hearing loss assessed using BERA test.Conclusions: Early detection and timely intervention can not only help prevent this silent handicap of deafness but also contribute to social and economic productivity of a community.

“…In difficult to test children where behavioral observation audiometry is not conclusive, ABR is the investigation which can detect the sensitivity of the ear, being useful for early detection. 19 Song et al, in their study to screen newborns with ASSR and DPOAE, concluded that ABR can be substituted with ASSR for screening, 20 while Celik O et al, concluded that ASSR is not a reliable for screening purposes, but as a complementary diagnostic investigation. 14…”

Objective: Hearing loss (HL) with a local prevalence of 5.7%, is the commonest childhood disability, requiring Early Hearing Detection and Intervention (EHDI) programs to reduce the disability burden. Knowing the degree, type and configuration of HL is prerequisite for appropriate amplification, with Automated Auditory Brainstem Responses (ABR) being commonly used for this purpose, however Auditory Steady State Response (ASSR) has been recently introduced in the region. This study was conducted to compare ABR to ASSR, as an early diagnostic tool in children under five years of age. Methodology: This cross-sectional comparative study was performed at the Auditory Verbal Institute of Audiology and Speech (AVIAS) clinics in Rawalpindi and Islamabad, from December 2016 to September 2017. It included thirty-two cases (n=32) who visited AVIAS clinics for hearing assessment and conformed to the investigative protocol using non probability convenient sampling technique, and subjected to both ABR and ASSR for comparative purposes. Correlations were calculated between the thresholds obtained by ABR and ASSR. Results: N=32 children (64 ears) with male female ratio of 2.2:1 and mean age of 33.50±17.73 months were tested with ABR and ASSR for hearing thresholds and correlation coefficient between 2KHz, 4KHz ASSR and average of both with ABR was calculated to be 0.92 and 0.90 and 0.94 respectively. Conclusion: ASSR provides additional frequency specific hearing threshold estimation compared to C-ABR, essentially required for proper setting of amplification devices.

“…The auditory temporal discrimination provides abundant information about the smallest time interval needed to resolve acoustic events.Existing Audiometry Test (AT) fails to assess the hearing perception and the variations in case of normal subjects. [4] Towards the same, a novel approach based on intensity, termed as the Absolute Threshold Test (ATT) has been developed to obtain the subjective hearing perception of normal individuals.…”

Psychophysics is one of the most important aspects to assess the auditory behavior in human beings. The present study has been successful in exploring the temporal resolution with respect to auditory stimulus thereby helping in the analysis of the auditory psychophysics in human beings which has been gaining wide acceptance in behavioral research. This research work concentrated on subjects with no known auditory pathological history, both males and females of different age groups, subjects exposed to noise (fabrication industry, chemical industry) and professional basketball players. The subjects were made to undergo conventional Audiometry Test (AT) as well as the Absolute Threshold Test (ATT) developed. A similar pattern was observed in the results of AT across all types of subjects. There were no eminent variations observed other than a characteristic dip between 4000 -6000 Hz. Hence it was concluded that the AT cannot assess the variations in hearing perception for normal individuals with respect to age, sex and occupational exposure. The Absolute Threshold (ATTh) obtained from the ATT were found to be varying in subjects with respect to age and sex wherein the males had a better ATTh than females. Also ATTh was found to deteriorate with age. ATTh was able to differentiate the hearing perception of the positively conditioned (basketball players) and negatively conditioned (chemical and fabrication industry) subjects thereby proving to be an efficient tool to assess the hearing perception in the conditioned and the control set of subjects. Hence ATT based approach could be very useful in sports training and rehabilitation approaches and hence can be a very useful tool in the assessment of auditory temporal resolution of human beings in various applications.
