Room Acoustic Design for Open Plan Interior in Dwelling House

Taiwanese dwelling house designs prioritize open space flexibility while also addressing the high-quality sound field requirements, which can be objectively simulated and verified post-construction. The living room, serving as the primary area for leisure activities, is often adjacent to the dining area or others. Ensuring optimal sound quality, necessitating control over sound reflection volumes in both the living room and adjoining areas. Firstly it is achieved by mitigating outdoor noise intrusion and minimizing indoor noise sources through strategic room acoustic design approaches that integrate broadband absorptive materials capable of effectively absorbing sound across various frequencies. Utilizing computer predictions alongside corresponding material performance allows for the reinforcement of sound magnitude while enhancing speech intelligibility and hearing intimacy during the early stages of design. Overall, This study aims not only to explore these issues but also to establish a sound environment conducive to achieving a basic quality listening field.
