一、前言室内声学研究的任务是要不断地为设计提供声学上最佳的指南。由于厅堂音质最终是要根据其建成后的主观评价来判断,因而,声学工作者不断在探求室内声学标准和主观评价之间的关系。很久以来混响时间做为唯一的标准来考虑,并根据厅堂的使用目的,在一定范围内选取其合适的数值。如今人们已得知,即使满足这个要求,音质的主观评价仍有差异。已经证实瞬态响应、混响衰减曲线的细微结构等是除混响时间外产生这种听感差异的原 I. Introduction The task of indoor acoustics research is to constantly provide acoustically best guidelines for design. As the auditorium’s sound quality is ultimately judged on the basis of its subjective evaluation, acoustics practitioners are constantly exploring the relationship between indoor acoustics standards and subjective evaluations. For a long time, reverberation time has been taken as the only criterion to consider, and according to the purpose of use of the halls, the appropriate value is selected within a certain range. Nowadays people have learned that subjective evaluation of sound quality is still different even if this requirement is met. Transient response has been confirmed, the fine structure of the reverberation decay curve is in addition to the reverberation time to produce this sense of difference between the original
