Abstract
Corn husk extracted from maize is a potential candidate for the application of noise reduction. The overall goal of this study is to investigate the acoustic absorption properties of corn husk. The effects of multi-layer structure on the acoustic absorption coefficient were studied. The results indicated that acoustic absorption was not improved with the increase of layers, while the acoustic absorption peak gradually moves to lower frequency direction. Furthermore, it has been observed that the increase of back cavity distance can also increase the absorption coefficient at low frequency range.
