Mathematical model of speech intelligibility in mosque with column pillars

The mosques in Malaysia are normally built in large scale with at least 280 m3 in volume. These large mosques usually have domes as partial of the ceiling and column pillars to support the large areas of the ceiling. The existence of domes and column pillars in large rooms can introduce a problem in...
