| Outline of Final Research Achievements |
Recently, microperforated panel (MPP) and permeable membrane (PM) sound absorbing structures, which have superior material properties from the perspective of hygiene demands, recyclability and flexibility of design, have been developed intensively. In this research, prediction methods of sound filed in practical sized rooms with MPP and PM sound absorbing structures were developed using finite element methods in time and frequency domains. In addition, the absorption performance of some absorbing structures was evaluated under actual installed conditions, and the effective sound absorber location was explored, in order to use MPP and PM absorbing structures effectively in room acoustic applications.
