Abstract
We discussed the correlation between physical and psychological quantities based on the data taken from the artificial sound field obtained in anechoic room. From the consideration of linear correlation coefficients, we can state the following: (1) Time vs. sound pressure ratio and the decay-time of the short tone pulse correlated better than others to aesthetic and lyric factors, and to voluminous and space factors. (2) Also, the time vs. sound pressure ratio correlated to the softness factor. (3) In comparison to the decay-time of the short tone pulse, the time vs. sound pressure ratio showed a better correlation to these psychological measures. (4) Tone pulse which was constant for the duration of 25 msec was available for the sound source of this type of physical measurement. (5) The assumption that there exists linear correlation between physical and psychological quantities was approved.
