Control and Analysis of Low Frequency Noise for Underground Transformer Room in Urban Residential Areas

摘要：

　　In this study we choose a transformer room from the residential buiding,and analyze the principles of the generation of sound source and noise pollution characteristics both out of and in the residential building,As the emission standard for community noise (GB22337-2008) required,it is more difficult for the indoor low-frequency range from 125Hz to 500Hz to reach the standard.A new controlled technology for decreasing vibration was designed for low frequency noise of transformer room combined with the measures of sound-absorption and sound-insulation,in order to solve the problem of meeting the standard for low frequency band spectrum.
