既有居住建筑附属地下换热站降噪研究

Research on noise reduction of the ancillary underground heat exchange stations in residential buildings

为了降低既有建筑附属用房产生的噪声对居民生活的影响、改善居住建筑声环境,对既有居住建筑附属用房地下换热站的噪声源以及噪声传播途径进行了分析;以既有居住建筑地下换热站室内噪声实测数据为基础,对室内环境的声学特征进行分析。在综合考虑居民的健康和舒适的基础上,提出了针对该附属用房的降噪处理改造设计方案。经过改造后的空间噪声明显降低,空间声环境指标达到标准要求,有效地改善了居住建筑的声环境。文中提出的改造设计方案为制定民用建筑附属用房声学设计标准提供了技术支撑。

To reduce the impact of noise generated by ancillary buildings on living condition and improve the acoustic environment of residential buildings, the noise source and the noise propagation routes of the underground heat exchange station of the existing residential building are studied in this paper. Based on the measured data of indoor noise in the underground heat exchange station of existing residential buildings, the acoustic characteristics of indoor environment are analyzed. From the comprehensive consideration of the health and comfort of residents, the noise reduction processing and transformation design scheme for the auxiliary building is proposed. The spatial noise after the transformation is significantly reduced, and the acoustic environment index of the living space after transformation meets the standard requirements, so that the acoustic environment of the residential building is effectively improved. The transformation design scheme proposed in this paper provides a technical support for the development of acoustic design standards for ancillary buildings in civil construction.
