摘要
建筑物内表面及其装饰材料的吸声性能,对室内声环境有着十分重要的影响。介绍了国家和国际标准对材料吸声性能采用的单值评价和产品吸声性能的分级方法。
The sound absorbing performance of building's inner face and decorated material has significant impact on the indoor acoustic environment. A method to determine the single rating value from the one-third-octave band measuring values of the sound absorption coefficient and the classification method based on the single rating value for sound material are described in this paper.
