Abstract(in English) In this paper, results of experimental measurement and numerical simulation of acoustic environment are shown for the music hall of Hakodate communication center. The reverberation time is measured with the method of Time Stretched Pulse (TSP) for between the center of stage and two different audience seats of the center and side of the audience floor. Using the ray tracing method with 3-D models of the music hall for empty seats and full seats, we investigate acoustic pressure distribution on the audience floor. More over we propose a method to improve the acoustic environment for the hall with diffusers of simple structure, and show that the proposed method is effective to equalize pressure distribution of the audience floor.
