Internal Damping damps out any ringing or vibrations in the cone structure that would otherwise color the sound.
内部阻尼将任何在锥体结构中的鸣响或震动阻挡出去，否则会产生杂音。

The example given in this paper shows that the method is feasible to calculate the dynamic properties and sound radiation of surface damping-treatment structures.
算例表明，用此方法分析计算表面阻尼处理结构的动态特性和声辐射是可行的。
