dc.description.abstractTo propose an appropriate design for sound diffusion through the walls of concert halls, computer simulations and a scale model were used to investigate the effect of diffusion and diffusion arrangements on the acoustic parameters of the concert halls. Two types of models were constructed and analyzed: 1) the 12 concert halls included in an Odeon simulation with reflective surfaces, and 2) the same simulation models with existing scattering coefficients. The effect of the overall wall diffusion in the concert hall was examined by analyzing the room acoustic parameters. Specifically, the position, area, and height of the diffuser were determined using various scale models. Through auralization evaluation in the 1:10 scale model, acoustic disturbance and the improvement in acoustic response through diffusion design were evaluated. The results show that the relative standard deviation values of the acoustic parameters as well as the reverberation time, early decay time, and sound pressure were reduced by sound diffusion through the wall surfaces.-
