Abstract (in Japanese) (See Japanese page) 
(in English) Numerical simulation of radiation of Distributed Mode Loudspeaker (DML) hasn't been reported from a point of view of diffused property of radiation. To operate sound field simulation with various types of loudspeaker will helps understanding "what is diffused property ". We made some simulation of behavior of vibrating panels using Finite Element Method with some driving conditions and boundary conditions. And we made simulation of sound field generated by vibrating panel. From simulations, we could show characteristics of DML on frequency responses and directivity DML. Also we could show the difference of sound filed between generated by pistonic panel and DML.
