| Abstract: | 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. |
