Sound absorption coefficient of carved wood panel with Islamic geometric patterns /

The use of Islamic geometric pattern is very common in mosques, and very often, the patterns are carved on wood, but because of unavailability of their sound absorption coefficients, these carved wood panels are not used for the acoustic design of the mosque although they contribute to sound Absorpt...

520 |a The use of Islamic geometric pattern is very common in mosques, and very often, the patterns are carved on wood, but because of unavailability of their sound absorption coefficients, these carved wood panels are not used for the acoustic design of the mosque although they contribute to sound Absorption. This research finds sound absorption coefficients of Islamic geometric patterns carved on wood using acoustical simulation software BEASY. This research finds common geometric patterns to find sound absorption coefficient of a representative pattern that can be carved on wood using acoustical package of simulation software BEASY. BEASY is used to simulate sound emitted from a source in front of a wood panel carved with Rub el Hizb to find sound intensity in front of the panel, and then using sound intensity technique sound absorption is calculated. Sound absorption coefficients are found by three methods, in the first method an anechoic room with a wood panel carved with Rub el Hizb inside it is simulated, sound source in this method is a point source. The second method simulates only the wood panel carved with Rub el Hizb in an infinite space with a point source. The third method simulates the panel in an infinite space with a sphere object as the source of sound.
