Primary Investigation Of Optimization On Sound Absorber By Finite Element Method

It is very pivotal to choose and dispose the sound absorption material in the architecture such as odeums and cinemas, etc. Its main function is to weaken the reflection of incidence voice, eliminate reecho voice, shorten and control the reverberation time, and meliorate the timbre condition of the rooms. Therefore, it is very necessary to investigate how to more effectively utilize sound absorption material in the times that people's request is higher of such view and act architecture.Distributing of sound field and position disposition of sound absorption material in room is an important part of room acoustics, and position disposition of sound absorption material and its sound absorption evaluation characteristic investigation is in laboratory to measure and analyze mostly. This thesis carries through introductory exploration to discuss distributing and position dispose prism sound absorber of sound field in room through computer simulation by finite element method.
