Abstract

In sound-conditioning in the room, three factors affect the quantity and quality of sound received by the listener: the sound source, shape, and space-forming material through 3 types of acoustic materials, namely, reflector, absorber, and diffuser. The presence of a diffuser can affect the absorption and crispness of the sound and the breakdown of sound energy. Although the space-forming corner also affects it. A room with space-forming corners elements allows for better sound quality, such as a room with a minimum flat area. This study raises the case of a prayer room with a volume of 3,500 m3. The structural factors of the existing building and the availability of funds require the use of the same material in the ceiling area. Based on these challenges, the problem in this study is to determine the effect of using planes and diffuse materials as a substitute for absorption materials. The methods used are simulation methods and comparative studies. The simulation uses CATT Acoustic to determine the need for acoustic quality in the room and then compares diffuse elements with the absorbent material model. The results showed that to absorb sound in the room could use diffuse material.
