Estimation of geometric parameters for micro-perforated panels and their effects on sound absorption performance
《Chinese Journal of Acoustics》2019年第2期215-226,共12页WANG Weichen XING Bangsheng GU Haixia MA Ran 
supported by the General Project of College Natural Science Research of Jiangsu Province(16KJD460002);the National Natural Science Foundation of China(51605209)
The geometric parameters of micro-perforated panels with irregular holes cannot be directly known,making it difficult to calculate the sound absorption performance.Therefore,we propose a method of estimating the geome...

Enhancement of low-frequency sound absorption of microperforated panels by adding a mechanical impedance被引量：14
《Chinese Journal of Acoustics》2015年第1期27-36,共10页ZHAO Xiaodan LI Xiao DING Rui 
supported by the Scientific Research Foundation for Senior Professional of Jiangsu University(11JDG096);the Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions((2011)6)
In order to solve the bad low frequency sound absorption of the Micro-Perforated panel （MPP） absorber, mechanical impedance was introduced in the back of the MPP absorber to form a composite structure. According to ...
