Comfort in buildings can be categorized into three types, namely thermal, visual, and audial comfort. Audial comfort itself has several parameters including reverberation time. The greater the reverberation time, the longer the noise in the room will decay, causing noise accumulation. This will certainly be very disturbing, especially if the room accommodates activities of preaching and worship. Many things affect the amount of reverberation time, including the shape of the building, room volume, interior design and interior materials used. Buildings with concave ceilings, such as mosques with domed roofs, have poor acoustic performance compared to buildings that have convex or flat ceilings because sound tends to be reflected and the reflections are accumulated at several points. The sound distribution is also less even when compared to buildings with flat or convex ceilings. Baitullzzah Mosque at the Adhi Tama Institute of Technology has a typical design of mosques in general, with a concave ceiling and hard materials in its interior, so it tends to reflect sound. The location of the mosque, which is on the edge of a main road, also allows noise pollution to occur in the worship space. This study aims to evaluate the performance of acoustics, in this case the reverberation time, analyzing the impact of the mosque location on the main road, and provide acoustic design solutions for the mosque of Adhi Tama Institute of Technology Surabaya. In general, the applied method was correlational research with relationship study strategy. The results were obtained by examining the relationship between several variables that affect the reverberation time, particularly the type of interior material and the surface area of the absorbent field used. The results showed that the acoustic comfort in the Baitullzzah mosque can be obtained by adding absorbency and replacing wall, ceiling and floor materials. This solution can also be used for noise management in similar mosques. 收起
