Abstract
Introduction and Aim: Aging of the auditory pathway is a complex phenomenon consisting of changes in the auditory processing along with a significant elevation of the hearing threshold. The aim of our study was to see the variation in interpeak latencies (IPLs) of Auditory Brainstem Responses (ABRs) with advancing age in males.
 
 Materials and Methods: It was an observational study conducted on 60 Indian male subjects aged between 20 and 80 years divided into three groups on the basis of age: Group 1: 20-40 years, Group 2: 41-60 years and Group 3: 61-80 years. Auditory threshold and ABRs were recorded and analysed for interpeak latencies (IPLs) – I-III,I-V and III-V in msec.The comparison of data between the groups was done using one – way ANOVA and Tukey Kramer multiple comparison test. The results were considered significantly different between the groups when ‘P value’ was ? 0.05.
 
 Results: It was found that there was no significant difference in the auditory threshold and interpeak latencies (IPLs) when comparison was made between the three groups.
 
 Conclusion: Hence we conclude thatage does not have any significant influence on neural conduction time of the auditory pathway which is represented by the IPLs in ABRs.

The synchronised activity of the auditory nerve and brainstem is represented by the ABRs (Auditory Brainstem Responses) called as the BAEPs (Brainstem Auditory Evoked Potentials)
Summary
Introduction and AimAging of the auditory pathway is a complex phenomenon consisting of changes in the auditory processing along with a significant elevation of the hearing threshold. Five waves are recorded in the human scalp recording that are labelled as I, II, III, IV and V with waves I, III and V being the most prominent [2] These waves represent neural conduction processes in the central auditory pathways and are used to measure peripheral auditory sensitivity, differentiate between cochlear and retro cochlear hearing loss and to evaluate the neurologic intactness of the brainstem [1]. These waveforms in normal subjects vary with age, sex, stimulus parameters and the recording system used. The interpretation of ABRs is an age dependant phenomenon [3]
