抄録

A series of measurements of sound pressure levels were carried out at waiting areas in hospitals; meanwhile, psychoacoustical survey questionnaires were conducted. Measurements of impulse responses were also carried out to extract reverberation time (T_<20>). As a result, the relationship between the L_<Aeq> and questionnaires reveals the statistical tendency that the subjective perception of acoustic condition turns to "bad" from "good" at the 60dB. The comparison of T_<20> and the average absorption coefficients (α) for waiting areas offer the hypothesis that the difference in ceiling absorption coefficients influences architectural acoustic condition.
