摘要
根据微穿孔板吸声体的准确理论,基于VC++6.0的软件平台,针对在生产实践中消除噪声的宽频带问题,编制了微穿孔板吸声体结构设计中的数值分析程序。通过吸声屏障设计计算的实例分析,对结构设计中的某些问题,如结构参数与吸声特性之间的相互影响等,进行了较为深入的分析和探讨。
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.
