The noise levels in the cochlea when a drill is used in the mastoid process have been calculated from vibration measurements on intact skulls of human cadavers and temporal bones. The results lend support to the conclusion that, in ear surgery the ipsilateral cochlea is exposed to noise levels of about 100 dB and the contralateral cochlea to levels 5-10 dB lower every time the drill is used. This noise trauma may account for some of the high-tone sensorineural hearing losses after tympanoplasty described by other authors.
通过对人类尸体完整头骨和颞骨进行振动测量，已计算出在乳突手术中使用钻头时耳蜗内的噪声水平。这些结果支持了以下结论：在耳部手术中，每次使用钻头时，同侧耳蜗暴露于约100分贝的噪声水平，而对侧耳蜗暴露于低5 - 10分贝的噪声水平。这种噪声损伤可能是其他作者所描述的鼓室成形术后一些高音感音神经性听力损失的原因之一。
