摘要
针对江苏常熟发电有限公司3号炉一次风机周围环境噪声的特点,从降低噪声源的噪声级、增加噪声在传播途径中的消耗、设法阻止噪声传播等途径进行了综合治理。治理后的平均噪声由105dB(A)降到90dB(A),达到了国家规定的工业企业噪声标准。
According to the noise characteristics of the first blowing fan,a comprehensive control method is proposed from reducing the noise level of the source,increasing the lose in the transport road and resisting its transportation.The control results are remarkable,the noise level is reduced from 105 dB(A) to 90 dB(A) and meets the standard requirement.
