| Summary |
Sometimes concerts and lecture meetings are held in membrane structure gymnastics. In such cases， sometimes sound troubles are occurred， because of the character of the structures. Sound fields were measured in 4membranestructures. 3 types sound absorption management were tried in the structure. (l)Absorption at the floor. (2)Absorption at walls. (3)Absorption at the ceiling. The results shows， not only the absorption at the floor， but also the absorption at walls and the ceiling is effective. The effectiveness of inside membrane are confirmed at the view points of sound absorption and transmittance of light.
