Abstract
In this paper, based on the fabricated wall panel used in original modular indoor substation, the optimal design of sound insulation property is conducted according to the relevant theoretical basis of sound insulation properties of wall panels, and the reverberation room method is used to test and study original and new wall panels. The study shows that the sound insulation of the sandwich panel after optimization has been greatly improved in both medium, low and high frequency areas, with obvious optimal design effect, and also there are significant engineering application value and social benefits in the noise control of substation.
