Background: Mobile phones have become an indispensable part of today's modern world. But with various day-to-day benefits, mobile phones also bring detrimental effects on the health of users. Ear being the closest organ in contact with phones, faces maximum effect of electromagnetic waves generated by them. Chronic exposure to these waves and sounds can result in permanent hearing loss. Hence, the present study was done to assess the association between hearing loss and duration of mobile usage.
Methods: This cross-sectional study was conducted on mobile phone users between the age group of 20 and 40 years in the Department of ENT, Rajindra Hospital, Patiala over 6 months (1 August 2022 to 31 January 2023). 600 volunteers were involved and divided into three groups based on the duration of mobile phone usage. Pure tone audiometry and DPOAE were used to assess the hearing loss in these subjects.
Results: A variable degree of hearing loss was observed on PTA and DPOAE in all three groups with a significant association between hearing loss and the duration of mobile phone usage. A higher proportion of sensorineural hearing loss was observed in the group with mobile phone usage of more than 1 hour per day for a minimum of 4 years as compared to those who used them for <1 hour per day for a minimum of 4 years and control group (p=0.001) which was significant statistically.
Conclusions: People using mobile phones for long hours are at higher risk of developing hearing loss, especially in the dominant ear.
