“…The widespread use of mobile have raised concerns about the possibility that exposure to the RF fields from mobile phones or their base stations could affect people's health, particular concern to the WHO is the fact that, developing countries are establishing this technology in preference to the more expensive fixed line systems. [6][7][8][9][10][11][12] Keeping in view the hazards of the mobile phones, the present study was designed to investigate the association of use of mobile phones and hearing loss. In our study, mean age was found to be 20.45±1.55 years in group A and 21.85±2.81 years in group B. Patel et al, 6 reported mean age was 26.17±2.65 in study group and that of controls was 26±3.93 years.…”

Introduction: Mobile phones as fastest means of communication, indispensable for daily life globally. The widespread use has given rise to concerns about the potential health hazards of its electromagnetic fields (EMFs) on human health. The present study was conducted to investigate the adverse effects of mobile phone usage on auditory functions and to study the pattern of hearing threshold in mobile phone users. Objective: The objective of the study was to study the effect of mobile phone on average pure tone audiometry (PTA) threshold of the person and to study the changes in the pure tone threshold at high frequencies such as 2 kHz, 4 kHz, and 8 kHz among the students with prolonged exposure to mobile phones. Material and methods: A cross-sectional study was conducted among 200 medical and paramedical students who have been using mobile phones for one year or more, divided in two groups. Group A- less than one hour per day and GroupB- more than one hour per day. The effect of mobile phones on the PTA threshold in the exposed ear and the nonexposed ear was also assessed. Results: The study shows that there is a significant difference in average air conduction (AC) and bone conduction (BC) hearing threshold among the exposed and the nonexposed ears (P < 0.05) especially at high frequency. A significant rise of both AC and BC threshold in group B more than group A also noted in this study. Conclusion: The study conducted shows changes in the hearing threshold with mobile usage. The technology along with comfort also brings some hazards, hence to limit the duration of usage of mobile phones.

“…In our study, aural block sensation (23%) followed by tinnitus (21.15%) and decreased hearing (7.69%) were the presentations among mobile users. Mobile phones have been used since 1983, and their use was estimated to include around 6 billion users in 2010 [5].…”

Introduction: The wide use of mobile phones in the world has raised the possibility of exposure to radiofrequency waves causing many side effects to the health of users, and even more in children. Aim of the study: To study the impact of radiofrequency waves of mobile phones on the hearing of the children in a tertiary care teaching hospital. Material and methods: We studied two groups of children of age less than 16 years. One group comprised 52 mobile phone users for more than one hour per day for more than one year, and the second group comprised 52 children who were non-users or used a mobile phone for less than one hour per day for less than one year. Results: The children using mobile phones for more than one hour (2-3 hours) per day for more than one year had 5 dB loss in 7.2%, 10 dB loss in 4.5%, and 15 decibel loss in 2.5% of cases. There was a 5 dB loss in 7.9 and 10 dB in 5.5% of cases in those using mobiles 3-4 hours per day. There was sensorineural hearing loss in 28.6% of the children and 3.6% in the control group. Conclusions: This study did not show any significant hearing loss in children using mobile phones.

“…The BC threshold of the exposed ear and nonexposed ear show statistically significant difference at the average threshold and threshold of all frequencies. These findings are similar to studies conducted by Ramya et al .,[ 12 ] Prajapati et al .,[ 15 ] Velayutham et al .,[ 16 ] and Panda et al . [ 17 ] and suggest a possible inner ear damage caused by prolonged usage of mobile phones.…”

Introduction:Mobile phones have become indispensable for daily activities, and people are exposed to them from an early age. There is, however, concern about the harmful effect of the electromagnetic radiation emitted from the mobile phones.Objective:The objective of the study was to study the effect of mobile phone on average pure tone audiometry (PTA) threshold of the person and to study the changes in the pure tone threshold at high frequencies such as 2 kHz, 4 kHz, and 8 kHz among the students with prolonged exposure to mobile phones.Methodology:A cross-sectional study was conducted among the medical students who have been using mobile phones for the past 5 years. The effect of mobile phones on the PTA threshold in the exposed ear and the nonexposed ear was assessed.Results:The study shows that there is a significant difference in average air conduction (AC) and bone conduction (BC) hearing threshold among the exposed and the nonexposed ears (P < 0.05). A significant rise of both AC and BC threshold at individual frequencies between the exposed and the nonexposed ear is also noted in this study.Conclusion:The study conducted shows changes in the hearing threshold of the exposed ear when compared with the nonexposed ear. There are however lot of unanswered questions which provide an interesting avenue for further research. Till concrete evidence is available the only feasible way to control its exposure is to limit the duration of usage of mobile phones.
