The Impact of Geometrical Structure of Domes on the Acoustic Performance within Mosques

Mosques are considered as one of the most significant architectures for Muslim, where they have evolved to attain the Islamic requirements. Various worship activities are done within these public architectures and these activities required various acoustical needs. The geometry of mosques and theirceiling is largely impacted on the acoustical characteristics. The domes are the most shape that utilized to construct the mosque ceiling. The geometric architecture of the domes represents one of the key factors that impact on the performance of acoustics within the mosque. Thus, this paper aims to determine the impact of geometric architecture of domes on the quality of acoustical characteristics within the mosque. The mosque of King Abullah has been selected as a case study to address this issue. Further, many mosques have been studied from the literature to determine the impact of the geometrical structure of the domes on the acoustic characteristics and speech intelligibility. Many parameters have been utilized to measure the acoustical performance like RT, clarity, dome volume, dome shape, dome height and the material utilized to cover the dome surfaces. Based on the studies within the literature and the case study within this paper, the impact of the geometrical structure of the domes has been determined, also the impact of these parameters on the sound quality within the mosque has been determined at the end of this paper.
