矩形隔声罩声衰减的预测
- PREDICTION OF SOUND ATTENUATION OF A RECTANGULAR ENCLOSURE
- 摘要：本文用统计能量分析的方法对一个放在扩散声场内的矩形隔声罩的声衰减进行了预测,计算了隔声罩声衰减随壁厚改变的变化,并讨论了罩内声吸收对声衰减的影响。
- Abstract：The sound attenuation of a rectangular enclosure placed in a diffuse sound field was predicted by using Statistical Energy Analysis (SEA). The variation of sound with the thickness of the enclosure wall was computed and the effect of the acoustical absorption in the enclosure on the attenuation was also shown and discussed.
- Key words：sound attenuation rectangular enclosure
