当前我国工业生产中 ,作业工人接触噪声的现状还未得到明显改善 ,劳动者健康仍受到噪声的危害。正确测量与评估工作场所噪声水平是评价噪声性听力损伤及有效预防和控制噪声危害的一项重要工作。对于稳态噪声我国目前已建立了较为成熟的测量方法[1] ,而对于非稳态噪声暴露的测量 In the current industrial production in our country, the status of workers exposed to noise has not been significantly improved and the health of workers is still endangered by noise. Correctly measuring and assessing the noise level in the workplace is an important task in evaluating noise-induced hearing impairment and effectively preventing and controlling noise hazards. For steady-state noise, China has established a relatively mature measurement method [1], while for unsteady noise exposure measurements
