All the lumber has the fine soundvibration performance, the difference of lumber soundvibration performance can the more directly reflect plate intensity difference.
木材都具有优良的声振动性能，木材之间的声振动性能的差别能较直接的反映木材强度差别。

In recent years, the technique of structural intensity has been an efficient means of solving sound and vibration problems.
结构声强技术是近年来解决噪声和振动问题的有效手段。
