The factor set includes thc rever beration time R T, the mean forte sound pressure level L,F, the lateral efficiency LE,the frequency characteristic of early decay time | EDT(f)|, and Vmax (10 lg LE), the maximuin variation of 10 lg LE in a hall. An example shows the evaluation procedure in detail. It seems that the fuzzy set method is fcasible for evaluating concert hall acoustics, because it can give a quantitative evaluation result on the fuzziness basis.展开更多
