摘要
简述统计能量分析（SEA）中几种非共振传输（近场、直接场、强迫运动）及共振（混响场）传输特性与处理方法，并用简单方法导出声场间一种强迫运动-非共振传输系数表达式，可以满足工程要求。
Some non-resonant transmission(nearfield, direct(or far) field, forced motion) and resonant transmis- sion (reverberant filed)properties in SEA were summarized. The non-resonant transmission(forced motion)coefficient expression between sound fields was derived in this paper, the accuracy for engineering application of the expression can be satisfied.
