| 摘 要： | 以电－声传递测量替代声－声传递或振－声传递测量的方法来分析封闭腔室内的声传递特性，尝试用该方法对车内部件的声辐射传递特性进行了实验研究，结果表明该实验分析方法对于确定产生车内噪声的主要部件，研究车厢内的声特性十分有效，并具有物理概念明晰、实施简便的显著优点。

| Abstract: | An experimental investigation on transmission characteristics of interior noise of a car is presented. In stead of directly measuring acoustic-to-acoustic transfer function, the electrical to-acoustic signal transfer function is measured to evaluate the potential contribution of the car's parts to the noise. The acoustic field in car is analyzed by the same way. The results give valuable reference for determining the main noise contributors and studying the sound transmission in car. The application shows that this novel method is easy to use in engineering. |
