Effect of Cell Phone Usage on Hearing Threshold

Abstract

Objective of the present study is to know the effect of cell phone usage on hearing thresholds. MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSION: There was a significant increase in hearing thresholds in mobile phone users associated with duration of usage.
