Research and application of sound absorption-insulation barriers in transformer substation

Fund Project:

Abstract: Low-frequency noise pollution is a focus environmental issue of power transmission and transformation project. Based on analysing the spectrum characteristics of transformer substation noise in Nantong area, composite sound barriers which have good performance in sound absorption and insulation were producted and also finded application in noise control engineering of 110 kV substation. The result of acoustic simulation and acceptance check monitoring suggested that sound barriers had obvious effect on noise reduction. Acoustic environmental quality of surrounding sensitive buildings could meet the requirements of relevant environmental standards.
