Description
As an important symbol in Islam, a mosque is built with architectural grandeur. Among
the characteristics is its high ceiling and it is usually constructed with a typical spherical
dome shape. Some mosques, however, are influenced by the local culture and the dome
can be of a different shape, such as pyramidal, as found in mosques in Malacca,
Malaysia. This paper presents an assessment of the internal acoustical characteristics of
a mosque having a pyramidal dome. The study is conducted by means of computer
simulation using CATT indoor acoustic software. Reverberation time and clarity are
taken to evaluate the intelligibility of speech. The effect of the angle and height of the
dome on the acoustical parameters is discussed. It is found that a pyramidal dome with a
steeper angle contributes to poor acoustic clarity.
