The objective of this study is to assess high frequency hearing (above 8 kHz) loss among prolonged mobile phone users is a tertiary Referral Center. Prospective single blinded study. This is the first study that used high-frequency audiometry. The wide usage of mobile phone is so profound that we were unable to find enough non-users as a control group. Therefore we compared the non-dominant ear to the dominant ear using audiometric measurements. The study was a blinded study wherein the audiologist did not know which was the dominant ear. A total of 100 subjects were studied. Of the subjects studied 53% were males and 47% females. Mean age was 27. The left ear was dominant in 63%, 22% were dominant in the right ear and 15% did not have a preference. This study showed that there is significant loss in the dominant ear compared to the non-dominant ear (P < 0.05). Chronic usage mobile phone revealed high frequency hearing loss in the dominant ear (mobile phone used) compared to the non dominant ear.
本研究的目的是评估在一家三级转诊中心，长期使用手机的用户中高频听力（8kHz以上）损失情况。前瞻性单盲研究。这是第一项使用高频听力测定法的研究。手机的广泛使用程度如此之深，以至于我们无法找到足够的非用户作为对照组。因此，我们使用听力测量方法将非优势耳与优势耳进行比较。该研究为盲法研究，听力学家不知道哪只耳朵是优势耳。共研究了100名受试者。在研究的受试者中，53%为男性，47%为女性。平均年龄为27岁。63%的人左耳为优势耳，22%的人右耳为优势耳，15%的人无偏好。本研究表明，与非优势耳相比，优势耳有显著听力损失（P<0.05）。与非优势耳相比，长期使用手机导致优势耳（使用手机的那只耳朵）出现高频听力损失。
