本文对接触不同吨位冲床的冲压工健康状况进行调查,发现他们除受100～116dB的脉冲噪声(保持值)作用外,还受较强的(40～104dB)背景稳态噪声的影响。结果工人听力受到损伤,心动过缓及心律不齐的异常率较对照组明显增高。并对复合脉冲噪声卫生评价进行讨论。
In this paper, we investigate the health of punching workers exposed to different tonnage punches and find that they are affected by strong (40 ~ 104dB) background steady-state noise in addition to impulse noise of 100 ~ 116dB (hold value). Results Workers hearing impairment, bradycardia and arrhythmia abnormal rate was significantly higher than the control group. The health evaluation of compound impulse noise is discussed.
