Propagation Characteristics and Renovation Strategies of Noise from a Certain Reactor in Residential Areas
In the process of urban renewal,the noise of substation reactors has an increasingly significant impact on surrounding residential areas.Firstly,the working principle and noise characteristics of the reactor are analyzed.Secondly,taking a substation as an example,the propagation path of reactor noise is determined,and a reactor noise propagation model was established.Thirdly,the characteristics of octave noise and its relation are deeply analyzed.Reactor noise is mainly concentrated in the low-frequency range of 100～500 Hz,which has a significant impact on residential areas.Finally,the transformation strategy is discussed from two aspects of sound source control and propagation path control.
