A pure tone air conduction audiometric evaluation was administered to 137 dentists and 80 physicians. The physicians were found to have better hearing threshold levels, notably in the 4000HZ center frequency range. The left ear of right handed dentists showed a greater loss of hearing ostensibly related to proximity to the noise source. Dental specialists showed a loss pattern similar to those of the general dentists. The findings suggest that there may be a cause and effect relationship between hearing loss and use of the highspeed dental handpiece.
对137名牙医和80名医生进行了纯音气导听力测定评估。结果发现，医生的听力阈值水平更好，尤其是在4000赫兹中心频率范围内。右利手牙医的左耳听力损失更大，表面上与靠近噪声源有关。牙科专家的听力损失模式与普通牙医相似。研究结果表明，听力损失与高速牙科手机的使用之间可能存在因果关系。
