声效率 meaning in English
acoustic efficiency
acoustical efficiency
Examples
- But to circular plate with large surface area , the vibrate modes generated is often so high that there is reverse phases existing , which result in a decrease in radiation impedance , electric - acoustic efficiency and the electric power , as well as poor directivity
然而对于辐射面积较大的弯曲振动圆盘，一般激励的振动阶数比较高，因此存在弯曲振动的反相区，导致换能器的辐射阻抗下降，电声效率和声功率降低以及指向性变差等问题。
