建筑业工业噪声污染特性分析

对某建筑公司所属企业的生产性噪声进行了监测,分析结果表明:厂区138个测点噪声Leq为74～112 dB,平均Leq为89.2 dB。83.3%的测点集中在80～100 dB区间,超标率达52.9%。噪声距离衰减呈高度负相关(r=-0.9902,p<0.01)。暴露于噪声环境下的生产人数占总生产人数的27.7%,暴露于90 dB以上的人数占全部暴露人数的84.8%。针对以上状况,提出合理建议和改良措施。 

Analysis on the Property of Industrial Noise Pollution in Building Company

Mornitoring and Analysis were conducted to the working noise in a building company. The result shows that equivalent sound levels (Leq) of 138 sites are in the range of 74--112 dB with an average of Leq of 89.2 dB. The percentage of sites with Leq in 80--100 dB is 83.3%. The rate of above standard is 52.9%. Distance noise-reduce is negatively related to height (r=-0.9902, p<0.001). The workers exposed in the noise environment account for 27.7% of the total workers. 84.8% of the workers exposed in the noise environment are exposed to the environment over 90 dB. Rational suggestions and improvement measures were put forward.
