通过对高层建筑设备层内空调水泵隔振工程实例分析，通过对设备层楼板的声强阵列测量，取得楼板表面法向辐射的声强分布图，经过分析，发现设备层楼板存在空气声传播途径。据此确定楼板隔声缺陷及其相对位置，为减低设备层楼下房间的噪声声级，取得较好的效果。
通過對高層建築設備層內空調水泵隔振工程實例分析，通過對設備層樓闆的聲彊陣列測量，取得樓闆錶麵法嚮輻射的聲彊分佈圖，經過分析，髮現設備層樓闆存在空氣聲傳播途徑。據此確定樓闆隔聲缺陷及其相對位置，為減低設備層樓下房間的譟聲聲級，取得較好的效果。

Based on the air conditioning water pump in high-rise building equipment layer vibration isolation analysis of engineering example, through acoustic intensity array measurement equipment on the floor, made the floor surface normal sound intensity distribution, radiation through analysis, and found the device layer slab has airborne sound transmission. To determine the floor insulation defect and its relative position, as the noise reducing device layer in the room below, has obtained the certain effect.
