To assess the immediate consequences of 60 minutes exposure to mobile phones on hearing function by determining changes in distortion product otoacoustic emission (DPOAE) and hearing threshold levels (HTLs).
This prospective control clinical trial study was carried out at the Ear, Nose and Throat Department, King Abdulaziz University Hospital, Riyadh, Kingdom of Saudi Arabia from July 2009 to July 2011. The data collected included age, symptoms experienced after exposure, and HTLs and DPOAE were recorded before, and immediately after 60 minutes of exposure to the same model of mobile phone.
Heat/pain was the most commonly reported symptom. In the test-ears, significant shift (p<0.05) was noticed in HTLs at 1000 and 2000 Hz but not at other frequencies, while non test-ears did not reveal significant shift in HTLs. Additionally, test-ears revealed significant differences (p<0.05) in DPOAE at 1000 Hz, 1400 Hz, 2000 Hz, and at the average of all frequencies, while non test-ears did not show significant differences.
Sixty minutes of close exposure to electromagnetic fields emitted by a mobile phone had an immediate effect on HTL assessed by pure-tone audiogram and inner ear (assessed by DPOAE) in young human subjects. It also caused a number of other otologic symptoms.
通过测定畸变产物耳声发射（DPOAE）和听力阈值水平（HTL）的变化，评估接触手机60分钟对听力功能的即时影响。
这项前瞻性对照临床试验研究于2009年7月至2011年7月在沙特阿拉伯王国利雅得阿卜杜勒阿齐兹国王大学医院耳鼻喉科进行。收集的数据包括年龄、接触后出现的症状，并且在接触同一型号手机60分钟之前和之后立即记录HTL和DPOAE。
热/疼痛是最常报告的症状。在测试耳中，1000Hz和2000Hz处的HTL出现显著变化（p<0.05），但在其他频率处未出现，而非测试耳的HTL未显示出显著变化。此外，测试耳在1000Hz、1400Hz、2000Hz以及所有频率的平均值处的DPOAE存在显著差异（p<0.05），而非测试耳未显示出显著差异。
在年轻受试者中，近距离接触手机发射的电磁场60分钟对通过纯音听力图评估的HTL和内耳（通过DPOAE评估）有即时影响。它还会引起一些其他耳科症状。
