Study Analysis of Acoustic Quality Assessment of Salman-ITB Mosque Using Ecotect Simulation

Abstract

The mosque is a place of worship for Muslims that has a significant impact on society. In performing worship, there needs to be tranquility and clarity of speech so that the conveyed message can be clearly and effectively transmitted. In this study, the space used for simulation is the prayer room of Salman Mosque. The aim of the research is to determine the condition, causes, and improve the acoustic quality of the prayer room of Salman Mosque. This research utilizes Ecotect software, focusing on measurements of Rays and Particles, reverberation time, and acoustic response. The data collection method used in the research is simulation method. The simulation results show that measurements using Rays and Particles display sound lines falling on the back wall surface, with sound travel times ranging from 35 milliseconds to 48 milliseconds. These values are close to the desired sound travel time limit. Measurements using reverberation time indicate that in empty building conditions (0% occupancy), the Reverberation time is relatively high at 1.65 seconds. With the mosque filled to 50% occupancy, the Reverberation time decreases to 1.27 seconds, and when fully occupied, it decreases further to 1.03 seconds. Measurements using acoustic response show a reverberation time measurement in the prayer space of Salman Mosque using Ecotect Analysis v5.50 to be 4.05 seconds. This result is below the SNI 1726-2012 standard, which states that the reverberation time in a prayer space should range between 6-10 seconds. Thus, the calculation results for Salman Mosque are below the SNI 1726-2012 standard and are considered good.
