객석의자의 흡음정도에 따른 청중착석의 영향

The present study investigated how the effect of adding listeners varies with the sound absorption of the theatre chairs. One-tenth scale model chairs and listeners developed for closely approximate the sound absorption characteristics of full scale chairs and listeners were used. The absorption coefficients of theatre chairs with varied added absorption with and without listeners were measured in a model reverberation room using the perimeter-to-area (P/A) method. The results show how the effects of adding listeners to the chairs vary with the magnitude of the absorption of the unoccupied chairs and with the presence or absence of carpet under the chairs.
