| Abstract: | One microperforated panel absorber is presented in this paper,which is used for replacing the old one.It is not only reduce the thickness of material,but also improve the coefficient of sound ab- sorption,and enlarge the frequency width of sound absorption.Therefor,it can improve the economic in- dex as most maximum limit.This wide frequency changed hole and high resistance absober has tested by Zhejiang environment protection and libration control speciality association,the coefficient of sound ab- sorption is all higher than normal microperforated panel absorber. |
