Study of reverberation time for different mosque structure

Abstract

In the process to define the acoustic quality for an enclosed room, there are numbers of method and indicators that can be applying. One of them is using the Reverberation Time (RT60) as indicators. Optimum RT60 based on its volume should result in good speech intelligibility where it is the primary concern for a mosque to be build. In this study, RT60 is used to identify which mosque that fulfills the feature of the best acoustic quality. The three kind of mosque involve are a mosque with 90% constructed of woods, mosque with 905 constructed with concrete and the last one is a mosque with combination of more than one material which is about 60% of concrete and 40% wood and glasses. After completing this task, it is define that the mosque with combination of 60% concrete and 40% wood and glass has the best reverberation time which fulfill the best acoustic quality for multi-purpose room among the three mosques.
