Abstract

This work assesses effects of the modern pyramidal forms versus the traditional forms on the acoustical qualities inside the Masjids (Mosques). For this purpose; three rooms were acoustically compared utilizing ODEON ver. 4.2. They are: a pyramidal room (MRM), the reference room (RR) and a right rectangular prismatic room (CUB). Results showed that MRM exhibits the shortest T in comparison with CUB and RR. In case of MRM, if its internal space was left free from any obstruction (columns or slabs like mezzanine); it has the highest values for speech indicators among the others (D₅₀ 0.41 (SI 90 %) and STI 0.24). CUB has the next shortest T whereas RR has the longest T. Results also showed that CUB and RR together have very close values for speech indicators (D₅₀ 0.36, and 0.375, (SI 86 %) respectively, and STI 0.24 for both).
