Effect of Electromagnetic Radiations of Smart Phones on Hearing by Brainstem Evoked Response Audiometry

Background: Electromagnetic radiations from smart phones alter and prolongs the conduction in auditory tract. Materials and Methods: Age between 18-30 years, Group 1, N=50 people had electromagnetic radiations exposure for 1-5 years and exposed more than 3 hours per day. Group 2, N=50 people had electromagnetic radiations exposure for greater than 5 years and exposed more than 3 hours per day. Headache, tinnitus, antipsychotic, anti-depressant drugs, smokers were excluded. Brainstem evoked response audiometry (BERA) was done. Online GraphPad calculator using Student unpaired t test data was analysed. It was a case control study. Results: BERA parameters like waves III, V, interpeak latencies at 90 dB and 2 KHz in Group 2 were prolonged in comparison to Group 1. Conclusion: Brain stem evoked response audiometry (BERA) records subclinical hearing loss in smart phone users at 2 KHz and 90dB.
