The present study investigated the possible effects of the electromagnetic field (EMF) emitted by an ordinary GSM mobile phone (902.4 MHz pulsed at 217 Hz) on brainstem auditory processing. Auditory brainstem responses (ABR) were recorded in 17 healthy young adults, without a mobile phone at baseline, and then with a mobile phone on the ear under EMF-off and EMF-on conditions. The amplitudes, latencies, and interwave intervals of the main ABR components (waves I, III, V) were compared among the three conditions. ABR waveforms showed no significant differences due to exposure, suggesting that short-term exposure to mobile phone EMF did not affect the transmission of sensory stimuli from the cochlea up to the midbrain along the auditory nerve and brainstem auditory pathways.
本研究调查了普通GSM手机（902.4 MHz，以217 Hz脉冲发射）发出的电磁场（EMF）对脑干听觉处理的可能影响。对17名健康年轻成年人进行了听觉脑干反应（ABR）记录，基线时不使用手机，然后在关闭EMF和开启EMF的条件下将手机放在耳边。比较了三种条件下主要ABR成分（波I、III、V）的振幅、潜伏期和波间期。ABR波形在暴露后未显示出显著差异，这表明短期暴露于手机EMF不会影响感觉刺激从耳蜗沿听神经和脑干听觉通路向上传输至中脑。
