Currently, mobile phone ownership and a number of users are very high in India and are increasing day by day. The prolonged exposure to electromagnetic radiations by using a mobile phone can have detrimental effects on the human body which also includes the auditory system. There is a dearth of research studies focusing on consequences of exposure to the electromagnetic radiation emitted by mobile phones on the hearing mechanism. Hence, the current study is aimed to investigate the influence of mobile phone usage on the auditory system through audiological evaluations such as pure tone audiometry, speech audiometry, and distortion product otoacoustic emissions (DPOAE). The study included 105 individuals who are mobile users and 38 subjects who are non-mobile users. The SPSS software version 16 was used to perform normality tests and independent t-tests. The results indicated statistically significant differences in the scores across the groups. In pure tone audiometry (PTA) the auditory thresholds were significantly high especially at high frequencies, and in speech audiometry, the speech recognition threshold (SRT) was significantly high in mobile phone users than nonusers. In fact, the amplitude of DPOAEs was also significantly less in mobile phone users compared to nonusers. The test results also revealed that the hearing sensitivity in the dominant ear (preferred ear for mobile use) is relatively more affected than the nondominant ear. Therefore, the study concludes that the prolonged use of mobile phone can diminish the hearing sensitivity over a period of time.
