建筑物内隔墙及楼板的隔声性能是评价建筑物质量的指标之一。国内外在如何评价隔声指数方面各有规定。国际标准ISO R717-1968“住宅隔声的评价”、我国制定的“住宅现场隔声测量规定”和“建筑和建筑构件中隔声测量标准”(征求意见稿)、1982年正式颁布的JGJ11-82“住宅隔声标准”,均首先规定了相应的空气声和撞击声的参考曲线,再将有关测试结果的频率特性曲线和该参考曲线比较,然后根据相应规定的最大不利偏差及不利偏差总和推算相应的空气声隔声指数和撞击声
Sound insulation performance of partitions and slabs in buildings is one of the indicators for evaluating the quality of buildings. At home and abroad how to evaluate the sound insulation index has its own rules. International Standard ISO R717-1968 “Evaluation of Residential Sound Insulation”, China’s “Provisions on Measurement of Residential Sound Insulation” and “Sound Insulation Measurement Standards for Construction and Building Components” (Draft for Comment), and the JGJ11- 82 “Residential Sound Insulation Standards”, the reference curves of air sound and percussive sound are firstly defined, and then the frequency characteristic curves of the test results are compared with the reference curve, and then according to the sum of the maximum unfavorable deviation and the unfavorable deviation correspondingly specified Calculate the corresponding air-acoustics index and percussion sound
