About 5.6 billion people use mobile phones worldwide. India ranks second position with about 885 million
users. Apart from its function of making calls, listening to music has become one of the popular functions,
the sound delivered via headphones at high intensities. The purpose was to assess the possible deleterious
effects of headphone usage on Brain stem Evoked Response Audiometry (BERA) in both genders. The study
involved the recording of BERA using 30 volunteers between the age group of 18-21 years. They were divided
into 2 groups. Group 1: Headphone users <3hrs/day. Group 2: Headphone users > 3hrs/day. Both the groups
comprised both genders. Data were compared by unpaired Student’s t test and one-way ANOVA. There was
no significant difference in peak latencies of waves I to V and inter-peak latencies between genders on right
and left ear of headphone users, except wave V (p<0.01)on the left ear of headphone users with latency
being more in males than in females. We conclude from the observation that prolonged headphone usage
has a negative influence on brain stem auditory evoked potentials and there was no remarkable difference
between the genders.
