为探讨掘进工同时接触局部振动和噪声,这种联合作用对工人永久性听阈位移(PTS)的影响,作者选某煤矿井下在噪声强度115~117dB(A)的环境中,使用Z轴最大振动计加权速度为25.3m/S2的风动凿岩机,日平均接触振动和噪声2.5~3h的男性掘进工326
In order to explore the influence of the simultaneous exposure of local workers to local vibration and noise on the workers’ permanent hearing threshold displacement (PTS), the author selected a coal mine underground in the environment with noise intensity of 115 ~ 117dB (A) Pneumatic rock drilling machine with a weighted speed of 25.3m / S2, male borrower 326 with daily average exposure to vibration and noise 2.5 ~ 3h
