Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2013, Vol 2, Issue 27
Abstract
[b]OBJECTIVE[/b]: Objective of the present study is to know the effect of cell phone usage on hearing thresholds. [b]MATERIAL AND METHODS[/b]: Seventy students from 20-30 years of age were divided into two groups. Those using cell phone for more than one hour a day for past 5 years form the test group and those using for less than one hour for less than 5 years form the control group. Pure tone audiometry was done on all the subjects. [b]RESULTS:[/b] There was a significant increase in hearing thresholds at all frequencies for both air conduction and bone conduction in both right ear and left ear, except for bone conduction at 4KHz. [b]CONCLUSION[/b]: There was a significant increase in hearing thresholds in mobile phone users associated with duration of usage.
