对上海浦东三桥试验住宅楼的现场隔声测量结果表明，砼小型空心砌块的分户墙，其计权表现隔声量和计权标准声压级差分别为48dB和50dB，普通钢筋砼空心预制楼板计权标准声压级差为49dB。墙体和楼板的空气声隔声均接近住宅隔声标准的一级要求（≥50dB）。 The on-site sound insulation measurement results of the experimental residential building at the Third Bridge in Pudong, Shanghai indicated that the weighted performance of the split wall of the small hollow block was 48 dB and 50 dB for the sound insulation and weighting standards respectively, and the ordinary reinforced concrete hollow prefabricated Floor sounding standard sound pressure level difference is 49dB. The sound insulation of the walls and floor slabs is close to the first-class requirement of the residential sound insulation standard (≥50dB).
