| Research Abstract |
A microperforated panel (MPP) is a thin panel or film with submillimetre perforations. In this study, various sound absorbing structures using MPPs are proposed. Each of the proposed sound absorbing structures was theoretically analysed, and the trial products of some of those structures were experimentally measured. The results show that those structures using MPPs can be used effectively in practice. The study also includes various aspects which are useful for practical applications of them.
