厅堂音质受多种因素影响,而各种因素对音质评价影响的程度也不相同,在进行主观评价时必须综合各种因素以获得较为满意的评价结果.基于上述原因,文中提出了音质评价的9个指标体系,利用一次歌剧演出的机会,采用模糊数学理论对某音乐厅进行音质主观综合评价,并得到了该音乐厅在歌剧类演出时的音质主观效果. The quality of the auditorium is affected by many factors, and various factors have different influence on the sound quality evaluation. In the subjective evaluation, various factors must be integrated to obtain more satisfactory evaluation results. For the above reasons, the paper proposes the sound quality evaluation 9 index system, using the opportunity of a performance of opera, using the fuzzy mathematics theory to make a subjective synthetical evaluation on the sound quality of a concert hall, and get the subjective effect of the concert hall in the performance of opera.
