摘要
城市居民密集区的变电站噪声引起的居民投诉颇多,必须采用较有效的隔声措施来达到治理目的。通过对一起受居民投诉的变压器引起的噪声监测,分析了变压器噪声的衰减特性和频谱特性,有针对性提出治理措施,包括采用钢结构框架、吸隔声墙体以及彩钢夹芯板屋面等,使大型变压器噪声超出城区环境噪声标准限值的问题得到解决。
Transformer noise in city residents concentration areas causes many complaints which may be managed well by tak- ing effective sound insulation measures. This paper introduces an example of noise monitoring caused by transformer, analy- zes fading and spectral characteristic of transformer noise and makes pointed references for manage including taking steel structural framing, suck sound insulation wall and color steel sandwich board house, and so on which may solve the problem that large scale transformer noise exceeds limit value of urban area environment noise standard.
