校园柴油发电机噪声治理

Noise Control of Diesel Generator on Campus

通过对某校园内柴油发电机房噪声的倍频带测试和环境噪声监测,分析了噪声超标的原因;通过机房隔声、吸声、强制通风、隔振等技术措施对发电机房进行了噪声综合治理。结果表明,所采用的技术可有效地降低发电机房对外噪声辐射,实现发电机噪声达标排放。

Through the test of octave band of noise and monitoring the environmental noise in diesel generator room of a certain campus,we analyzed the causes of noise exceeding, and then controlled the noise comprehensively through sound insulation and absorption, forced ventilation, vibration isolation, and other technical measures in the generator room. The results indicate that the technique used is effective in reducing the genera- tor room＇ s noise radiation to outside, and the noise from generator can be compliance with the discharge standard.
