Reverberance in relation to the orthogonal factors of sound field
Shin-ichi Sato, Yoichi Ando

As an application of theory of subjective preference, this paper discusses reverberance as a typical overall response of the sound field. The scale value of reverberance obtained by applying speech and music signals. Results show that the scale value of reverberance may well be expressed by the four orthogonal factors of the sound field. As similar manner to the scale value of subjective preference, we can calculate those of reverberance at every seating position in concert halls or opera houses.

Key words: Reverberance, orthogonal factors
