摘要
标准是定量化和研究的基础。对《建筑和建筑构件隔声现场测量标准》实验验证得出结论:新标准与老标准在区分频率方法、测量频率扩展、测点布置、背景噪声修正、单值评价方法等方面有区别也存在连续性;新标准等同采用国际标准是可行的。
Through experiments on the proposed national standard （GB/T） Field Measurements of Sound Insulation in Buildings and of Building Elements, it is concluded that there are some differences in averaging time, frequency range of measurements, correction for background noise and expression of results between the new standard and the old version. It is feasible to make the national standards （GB）, Acoustics Measurement of Sound Insulation Building Elements, Part4： Field Measurements of Airborne Sound Insulation Part 7： Field Measurements of Impact Sound Insulation of Floors, identical （IDT） to ISO.
