Abstract:
In order to examine the accuracy of acoustic scale modeling, the experimental results of a 1/10-scale model study performed for acoustical design of a concert hall and those measured in the full-scale hall after the construction are compared. In the scale model study, the impulse responses were measured by the direct method using a spark discharge source and monaural and binaural microphone systems. For the measurement of the binaural impulse response, a 1/10-scale dummy head system was made on a trial basis. In the real hall, impulse responses were measured by the sweep-pulse method using a dodecahedral omnidirectional loudspeaker and monaural and binaural microphone systems. The monaural impulse responses were measured at the corresponding points in the scale model and the real hall, and such quantities as D50, C80, and Ts were obtained and compared. The binaural impulse responses measured in the model and real hall were convolved with the same sources of a variety of music and presented to the subjects through a transaural reproduction system using two loudspeakers. Through these quantitative and subjected investigations, a fairly good correspondence has been found between the scale model and the real hall.
