Application of Computer Aided Design in Structural Design of Microperforated-Panel Sound Barrier

On the basis of the general theory of microperforated-panel absorber, numeric analysis program is designed in structural design of microperforated-panel.This program is designed by the software "VC++ 6.0" and aimed to deal with the problems about broad frequency band when nosie is eliminated.By analyzing examples about designing sound barrier with this program,some questions in sturctual design,such as the influence between structual parameters and sound absorption characters,are deeply analysed and discussed.
