高层楼供水系统噪声源的识别

IDENTIFICATIN OF NOISE SOURCE OF PROVIDING WATER SYSTEM OF HIGH BUILDING

采用功率谱分析、相干分析、模态分析相结合方法 ,对高层供水系统振动、噪声进行了分析 ,找出其主要的噪声源及其主要频率成分 ,从而为治理噪声提供可靠的依据。

In this paper,though using frequency spectrum analysis?coherence analysis and mold analysis,we identify the noise source of this system.It provides a reliable foundation for reducing vibration and lowering noise level of machine.
