| 摘 要： | 采用符合GB/T3241规定的倍频程滤波器所测量的倍频带声压级,与室内噪声频谱分析倍频带中心频率为31.5Hz、63Hz、125Hz、250Hz、500Hz成线性关系的方法,来判定室内结构传声值是否超过国家标准.多方位测试声波在传递过程中的最高峰,使结果具有较高的精密度和准确度,是一种可靠的分析方法.

| Abstract: | The indoor sound transmission of structure is determined whether it exceeds national standard by the method of linear relation between sound pressure level in octave band determined by octave filter,in accordance with GB/T3241 and indoor noise spectrum analysis times frequency band,whose centre frequencies are 31.5 Hz,63 Hz,125 Hz,250 Hz and 500 Hz.The highest peak during the transmission process is catched by the method of multi-faceted test in order to obtain precise and accurate results.It is a reliable ... |
