【摘要】 对接触脉冲噪声的锻压工和冲压工进行了调查,其脉冲噪声强度波动在118—135dB(A)之间(峰值),对工人听力已有不同程度的损伤,心电图在低工龄组有改变。本文还分析了脉冲噪声引起听力损失与暴露时间有密切关系,同时对两工种的脉冲噪声还存在较高的背景稳态噪声所产生的复合性噪声进行了讨论。更多还原

【Abstract】 The paper dealed with the impacts of impulsive noise on the forgers and punchers exposed to a noise level of 118-135dB(A).The results showed that the hearing ability of the workers had been injured in different degrees.ECG changes were observed in the workers of short length of service. High correlations between hearing loss and exposure time were formed.Combined noise caused by impulsive and steady-state background noise were biscussed.更多还原
