Abstract
Many dentists believe that noise generated from high-speed drills results in a significant loss of hearing. Audiological evaluations, consisting of hearing thresholds at eight frequencies (500 to 800 Hz) and impedance audiometry, were done of 70 dentists from eight specialties. No statistical decrease in hearing thresholds appeared in either the speech or high frequencies when the dentists were compared with a normal, age-adjusted population.
摘要
许多牙医认为高速牙钻产生的噪音会导致听力显著下降。对来自八个专业领域的70名牙医进行了听力学评估，评估包括八个频率（500至8000赫兹）的听力阈值和阻抗测听。将这些牙医与经过年龄调整的正常人群进行比较时，言语频率或高频的听力阈值均未出现统计学上的下降。
