内容記述 | The SEA (statistical energy analysis) method can accurately predict the sound transmission loss of a finite wall. However, there is a large discrepancy between the calculated value and the measured value at lower frequencies, since the random incidence mass law deduced for the infinite panel is partly applied in this method. In this paper, to improve this point, the radiation factor derived by investigating the directivity characteristic of transmitted waves through a finite wall was introduced into the coupling loss factor between source and receiving rooms. The experimental and theoretical values agreed well over a wide frequency range. | |||||
