抄録

We subjectively evaluate the acoustics of rooms and the qualities of acoustical instruments by evaluating musical sounds, speech sounds, and others passing through them. In such a case we had expressed the evaluations by some descriptive adjectives such as "rich", "clear", "resound" and so forth. But there are a variety of expressions to describe the impression of such sounds, and it is uncertain what and how many adjectives we should use. Judging from the number of physical factors influencing those sounds, we expected that it is possible to select a limited number of adjectives sufficiently evaluating those sounds and made two experiments. The first experiment was made from the standpoint of room acoustics. 15 differentlyconditioned sounds made with a reverberation equipment were rated on 21 seven-category scales defined by polar-opposite adjectives. As a result of factor analysis of the intercorrelation between scales by the centroid method, four nearly orthogonal factors were extracted; (1) the aesthetic or lyric factor, (2) the one expressing "volume" and "extent", (3) the one expressing "brightness" and suchlike, (4) the one expressing "softness" and suchlike. The secound experiment was made by varying the lowest resonance of a dynamic loudspeaker by means of a simulator. The ratings were made by the Scheffe's method for pair comparison, and the result proved consistent with the first one.
