Assessment of auditory evoked potential in long-term mobile phone users.

Mobile phones emit strong electromagnetic wave which causes structural and functional changes in the cell membrane within the central nervous system especially auditory system. The effect of duration of mobile phone use on auditory function was examined One hundred and seventy three long-term mobile phone users aged around 17-39 yrs (both male and female) were recruited in this study. The subjects were divided into three groups according to their age Group I (17-19 yrs), Group II (20-29 yrs), Group III (30-39 yrs). After getting informed consent the subjects were instructed to fill the questionnaire for the history related to our study, conduction deafness auditory brainstem response in both the ears were assessed. Significant difference was observed among three groups in their duration of mobile phone use. Latency of Waves in three groups showed significant difference. The average latency (both right and left ear) of waves I-V was found to be prolonged in Group II when compared to Group I and Group III. Interpeak latencies I-V and I-III showed differences among three groups. The findings of present study showed abnormalities in the conduction of electrical signals in different levels of auditory pathway.
