Based on the noise survey for 1034 plants and 11794 equipments as noise sources in 9 professions and 9 provinces in China, referred to ISO/DIS 1999·2 (1985)"Acoustics-Determination of occupational noise exposure and estimation of noise - niduced hearing impairment" as well as the national standard of China "The noise hygiene standard for industrial enterprises", the hearing threshold level associated with age and noise (HTLAN) and its relation with hearing threshold frequency associated with age(HTLA)for the...

Based on the noise survey for 1034 plants and 11794 equipments as noise sources in 9 professions and 9 provinces in China, referred to ISO/DIS 1999·2 (1985)"Acoustics-Determination of occupational noise exposure and estimation of noise - niduced hearing impairment" as well as the national standard of China "The noise hygiene standard for industrial enterprises", the hearing threshold level associated with age and noise (HTLAN) and its relation with hearing threshold frequency associated with age(HTLA)for the workers under 85,90,95,100 dB of noise exposure level LEx.T.8h at 500, lK,2K, 3K,4K,6KHz are obtained in this paper.The formulas for calculation of LAeq, HTLAN,H', H' = H + N-HN/120 in ISO/DIS 1999·2 and Gauss distribution are used in the work. The standard ISO/DIS 1999·2 has been proved to be applicable in China.

本文参考ISO/DIS1999·2(1985)《声学──职业性噪声测定与噪声引起的听力损伤评价》资料,结合我国“工业企业噪声卫生标准”,对九省市九个行业、1034个工厂、11794个声源和部分噪声暴露者听力等的实测结果,采用ISO/DIS19999·2标准中给出的LAeq的计算公式及对噪声暴露工人听阈值的计算公式求得其听阈值(HTLAN),按高斯分布法取得暴露声级LEX,8h为85、90、95、100dB的工人听阈频率在500、1000、2000、3000、4000、6000Hz的不同工龄组噪声暴露人群的听阈值(HTLAN)及职业性非噪声暴露人群听阈值(HTLA)的关系值。研究结果证明ISO/DIS1999·2也适用于我国。

The noise-reducing effects of the cotton-yarn earplugs was evaluated by comparing the hearing threshold value of ear before and after the earplug wearing among 30 noise-free workers.The result showed that at high frequency section, the plug the diminution was shown as much as 16.25 to 21.17 dB. However, without an apparant diminution at phonic frequency section. It was clear that the plug had a diminishing effect for high frequency noise without interfering the phonic exchange. The average diminished value was...

The noise-reducing effects of the cotton-yarn earplugs was evaluated by comparing the hearing threshold value of ear before and after the earplug wearing among 30 noise-free workers.The result showed that at high frequency section, the plug the diminution was shown as much as 16.25 to 21.17 dB. However, without an apparant diminution at phonic frequency section. It was clear that the plug had a diminishing effect for high frequency noise without interfering the phonic exchange. The average diminished value was 13.86dB. Under the noise level not greater than 104dB(A) wearing of cotton-yarn earplug can keep the noise level well within the permissible standard.

本文以非噪声作业青年30名为受试者,佩戴棉纱耳塞,用真耳阈值法作60耳的棉纱耳塞隔声值评价。实验结果表明:棉纱耳塞对高频段衰减声强达16.25~21.17dB,对语频声信号衰减较少。这样,既有一定的隔声值,又不妨碍在工作环境中言语的交流。棉纱耳塞隔声值13.86dB,在噪声强度不超过104dB(A)的情况下,佩戴棉纱耳塞可将噪声衰减到符合《工业企业噪声卫生标准》中现有企业暂时达不到标准参照表范围内。

It is pointe that improper selection of measurement points and time interval of measurement in noise environmental impact assessment may lead to incorrect measurement and prediction results. Correct layout for measurement points and selection principles for measurement time interval are proposed so that the results obtained can be in good agreement with the practical situation of noise environment before and after the completion of a consturciton project.

工业企业噪声环境影响评价中,由于测点与测量时段选择的不妥,导致测量及预测值“以偏代全”的结果;本文提出了测点合理布设与测量,预测时段科学选择的原则,以使测量与预测结果能较好地符合项目建成前、后噪声环境实际状况。
