| Abstract(in English) | This report deals with some analyzing methods of closed space acoustics using Image Theory and Image Diffusion Theory. The accuracy and validity of the following six methods which smooth image sound sources in different ways are discussed. i)smoothing all sources, including real source. ii)smoothing image sources. iii)smoothing except 1st image sources. iv)smoothing except 1st and 2nd image sources. v)smoothing except 1st to 3rd image sources. vi)smoothing except image sources within equal radius of room. The distributions of sound presser level around a sound source are calculated using these methods and compared with the results measured in an actual room. |
