摘要
换热设备是高层建筑内的主要噪声源之一。结合实际项目对某个高层建筑内换热设备噪声及其传播途径进行分析,认为水泵和换热器是主要噪声源,其传播途径以结构传声为主,直传声为辅。根据降噪量要求对设备间采用简易消声室设计。其室内声学指标均达到预期目标,改善环境,取得良好的社会效益。
On the basis of investigation and analysis of noise source and transmission path in highrise building with heating plant, the noise of water pumps and heating plant were considered as main noise source in this paper. The transmission path of structure-borne sound is main, and direct transmission secondary. Simple anechoic chamber was used for noise reduction. In conclusion, acoustic characteristics of indoor achieved expected goal. The noise reduction also brings positive environment and social influence.
