This study endeavors to meticulously examine the phenomenon of high-frequency hearing loss, specifically frequencies above 8 kHz, within the demographic of prolonged mobile phone users in a tertiary Referral Center. Potential single blinded study. This is the first study that has used high-frequency audiometry. The extensive utilization of mobile phones has reached such a significant magnitude that our endeavor to identify an adequate number of individuals who do not use mobile phones for comparison purposes, as a control group, has proven to be unfeasible. Therefore we did the comparison between the non-dominant ear & the dominant ear using audiometric measurements. The study was a blinded study where in the audiologist was not aware about the dominant ear. A total of 200subjects were studied. Of the subjects studied 56% were males and 44%females. Mean age was22. The left ear was dominant in 65%, 21% were dominantin the right ear and 14% did not have a preference. This study has demonstrated a noteworthy disparity in hearing loss between the ear considered dominant and the ear considered non-dominant (P 0.05). Prolonged mobile phone usage has unveiled instances of high-frequency hearing loss in the ear identified as dominant. (mobilephoneused) compared to the non dominantear.
