Freefield to Eardrum Transfer Function (FETF) is one of the major factors influencing the identification of the sound source direction.
自由声场至耳膜的传递函数(FETF)被认为是影响辨别声源方向的主要因素之一。

The sound pressure at near distance under freefield was computed by using the wave number integration and the basic characteristics of the radiated noise were analyzes.
利用波数积分方法仿真计算了该模型在自由场条件下的近程声场，并分析了近场辐射噪声的基本规律。
