Effects of absorption elements and stage set on the stage house acoustics in a proscenium hall

چکیده
Acoustical characteristics of a stage house and their effects on auditorium acoustics were investigated in a proscenium hall using computer simulation and scale models. The effects of a fly tower, the upper part of a stage house, were investigated with variable upper batten densities and covering materials. In addition, influences of the lower part of the stage house were examined by controlling the installation of absorptive finishing materials. As a result, it was found that effects of banners inside fly tower could be constant when the ratio between the banner and fly tower volume become over 13.0%. Absorptive finishing materials on the lower stage structure were also found to be influential on stage acoustics. Finally, as several types of stage sets are utilized for the lower stage structure during performances, stage sets were classified into three types, and their effects on the stage and auditorium acoustics were investigated.
