Abstract
Because of its religious and social function, the mosque is a place of exchange and knowledge transfer of this knowledge, through the preaching of the imams in the form of speeches and reading the Qur'an during prayer. The mosques are therefore examples of public institutions where it is necessary ensure acoustic comfort, in order to obtain a good quality of listening. The mosque is also considered a building that has
specific features associated with room acoustics, by its function as a place of listening; this characteristic has a direct impact on the design choices and consequently on user comfort. Thus, the quality of acoustic environments inside the mosque is strongly related to choices of design developed by the architect that must take into account in the beginning of the design; to ensure good sound quality, which unfortunately is
far from the case. Our study attempts to answer the needs of designers, by assessing one of the most important criteria in room acoustics: the reverberation time. We will use for this purpose, the modelling and simulation tool to predict the acoustic quality of mosques by integrating the materials performance, which we will take it as a criterion of acoustic quality evaluated by the reverberation time. I use it in my research, acoustic simulation software EASE 4.4. In the area of room acoustics, these programs have reduced the complexity of the description of sound propagation phenomena in space. They allowed a simplification and mastery of acoustic phenomena. In second step, we will through different choices of materials, trying to optimize our reverberation time. This diagnosis can show us about the importance and contribution of each material for optimum sound quality inside the mosques.
