Tehran concert hall—a virtual specimen indicative the conversion processes from architectural design to acoustical remedies.

Abstract

Over the last year of the B.Sc. period it was investigated by the author to design a 1200‐seat concert hall as the thesis project. Now the quoted project has been enriched by the acoustical aspects of the concert hall design regarding the acquired capabilities during the M.Sc. studies. It has become prevalent these days to peruse and analyze the acoustical parameters of enclosures through the different acoustical simulation software such as Odeon 9, CATT‐Acoustics 8, EASE 4.1, and Ramsete 2.5, either before or after their construction as an objective assessment but interpreting this data is a real challenge.

The diffusers design as a geometrical shape with design factors of height, surface coverage and orientation in addition to their location will be studied computer aided to improve the acoustics in this virtual concert halls.
