Abstract:

The purpose of this study is to evaluate the subjective preference of a simulated sound field by listeners in changing subsequent reverberation time T[inf sub] using vocal sources. A great deal of effort has been made in the study using music or speech [for example: Ando et al., Acustica 50, 134--141 (1982); Ando et al., J. Acoust. Soc. Jpn. 39, 89--95 (1983), in Japanese]. Subjective evaluation using vocal sources has never been examined, although vocal performance is often played in concert halls and opera houses. Subjective preference tests were conducted changing T[inf sub], which is one of the four objective parameters in relation to subjective preference of sound field. Individual differences of subjective preference as well as global preference are also considered.
