Most studies of the effects of noise upon hearing have dealt with continuous noise exposure. Previous reports on intermittent exposure to noise concluded that it causes less damage to hearing than does continuous exposure to noise of the same intensity. In this investigation, 12,000 workers were screened to find 295 subjects who met the strict criteria of the study. Most of the subjects were exposed to jackhammer noise at peak levels of 118 dBA. Intermittent exposure to intense noise results in very severe loss in high frequencies but relatively little or no hearing loss in the lower frequencies even after many years of exposure. This differs substantially from the effects of continuous exposure to noise of the same intensity. It remains to be determined whether this pattern of hearing results from intermittent exposure to all sorts of noise or only from the kinds of sources investigated in this study.
大多数关于噪声对听力影响的研究都涉及持续的噪声暴露。先前关于间歇性噪声暴露的报告得出结论,与相同强度的持续噪声暴露相比,间歇性噪声暴露对听力造成的损害较小。在这项调查中,对12000名工人进行了筛查,以找出符合该研究严格标准的295名受试者。大多数受试者暴露于峰值水平为118分贝的手提钻噪声中。即使经过多年暴露,间歇性暴露于高强度噪声会导致高频严重损失,但低频听力损失相对较小或没有听力损失。这与相同强度的持续噪声暴露的影响有很大不同。这种听力模式是由于间歇性暴露于各种噪声还是仅由于本研究中调查的噪声源类型所致,仍有待确定。
