抄録

Many calculating methods of the sound transmission loss of double layer wall have been developed since A.LONDON presented the wave equation of double layer walls. 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.
