Application of microperforated elements in axial fan noise control and silencer design

The microperforated panel (MPP) is considered to be an alternative sound absorbing material, which could replace the traditional glass fibers and other porous materials because of its sound absorbing characteristics in a wide frequency range. The MPP is also very useful in various human involved environments because it is less harmful to human respiratory system than traditional sound absorbing materials, meaning more hygienic. Therefore in this study, microperforated panels were used in fan noise control and in acoustic silencers, where both of the devices are easily accessible by humans.
