摘　　要：从减振、隔振、吸声和隔声等方面采取措施可以降低管道排水噪声对室内环境造成的声污染。在实验室内模拟卫生间坐便器排水产生管道噪声的情景,并对管道采取包覆、加管道井等降噪措施,采集不同条件下的声学数据,并从中寻找到可以表征降噪措施性能的关键数据。The measures of vibration reduction,isolation,sound absorption and sound insulation can reduce the sound pollution caused by pipe drainage noise to indoor environment. In the laboratory,the scene of pipe noise generated by toilet seat drainage was simulated,and noise reduction measures such as cladding and adding pipe wells were adopted to collect acoustic data under different conditions,and key data that could represent the performance of noise reduction measures were found.

关 键 词：排水噪声 情景模拟 包覆管道井 降噪
