Designing an appropriate balance between sound reflection and absorption is essential in acoustic environments such as concert halls and live music clubs. While traditionally based on in-situ measurements, recent advances in computational power and acoustic simulation software have enabled numerical approaches, allowing for more efficient and accurate prediction and optimization during the design phase. The open-source software ADVENTURE_Sound is one such tool. It enables large-scale analysis of high-resolution models with tens to hundreds of millions of degrees of freedom on various parallel computing environments, while maintaining exceptionally high parallel efficiency. In this study, the author constructed a large-scale 3D model of a live music club, consisting of tens of millions of degrees of freedom, based on 3D scan data obtained from the actual venue. The model was analyzed using ADVENTURE_Sound under various sound absorption conditions. The study verified the optimal placement of sound-absorbing materials necessary to achieve improved sound quality in the live music club.
