| 摘 要： | 加入用于计算室内声学参数的AURA模块后,EASE模拟室内声场更为便利.尝试用EASE4模拟一窗口遮阳板的降噪效果,考察遮阳板不同设置时室内声压级的变化情况,结果表明,安装遮阳板后,室内平均声压级小约2 dB,水平式遮阳板的降噪效果比垂直式大约3 dB；遮阳板做吸声处理时,室内平均声压级下降约5dB.

| Abstract: | AURA module of EASE is used,it is more convenient to calculate sound field of a room.EASE4 is used to calculate the noise reduction of sun shading with different settings.The result shows that firstly,the average SPL of the room with sun shading is 2 dB less than that without sun shading,secondly,the noise reduction of horizontal sun shading is 2 dB more than the vertical one,thirdly,the SPL is 5 dB lower after the sun shading filled with absorption material. |
