Abstract
The design of an enclosure for speech activities (mosques, lecture
halls, theaters, classrooms, ... etc.) is not only an architectural matter,
whereas, the success of this enclosure in the function which it is build for
depends on how the audience will perceive the sound. Because sound
energy behaviour depends mainly on the enclosure form, finishing
materials, volume, and all other architectural considerations, a tool for
sirnu lation of sound energy in closed spaces has been established. Most
of these acoustical simulation models are acoustically oriented, in other
words, they are designed to be used by Acousticians with their technical
terminology. This thesis proposes ”A menu tree of an interface for
acoustics simulation in computer aided architectural design”, to
provide the Architect with a tool that could be used in the architectural
design process of speech halls. This proposed menu tree is based on
expert system technique. using an acoustical knowledge base, to guide
the Architect through all the design process from the acoustical point of
vj ew til reduce the acoustical problems. and ensure that the designed
enclosure is acousucally successful.
