摘要
利用弯曲振动法测取了纤维板的声振动参数并进行了分析比较,结果表明:密度大的纤维板其振动加速度较大,振动能量损耗较低,声反射能力较强,但声辐射能力较弱;厚度小的纤维板其振动加速度较大,声反射及声辐射能力均较强,但振动能量损耗较高。
The acoustic vibration parameters of fiberboard were measured by flexural vibration. The results show that the high density fiberboards have high vibration acceleration and acoustic reflex with low wastage of vibration energy and weak acoustic radiation ; that fiberboards with smaller thickness have high vibration acceleration, acoustic reflex and acoustic radiation with high wastage of vibration energy.
