But none of them can predict sufficiently the sound transmission loss in the case of random incidence. In this paper an equivalent distributed constant circuit was introduced to double layer walls, and the sound absorbent material in the cavity was strictly simulated using the equivalent circuit. It was verified that experimental results agreed with theoretical values satisfactorily.}, pages = {85--94}, title = {多孔質吸音材を充填した二重壁の音響透過損失について}, volume = {25}, year = {1983} }
