Optimization And Numberical Modeling Of Sound Absorber

Sound Absorber as the main technical means of hall acoustic design and noise control is used extensively.It can be used to control reverberation time of hall,some public traffic building,such as the sound absorber at architetural celing plate and wall in the airport lounge of aerodrome and the waiting room of station ect, eliminate the acoustic defects as echo and sound focus in hall and so on to enhance sound insulation of light and thin wallboard, using sound proof cover and acous noise-barrier for machine equipment can enhance its depressed noise effect,such as reduce the noise in room or industry mill building,the pipe alley muffler at arichetecure air handing and air condintion system debase the noise in pipe alley.So that ,no matter what controlling reverberation time,reducing noise,improving sound diffuseness and eliminating acoustic defect,that need using sound absorbers,research of acoustic characteristics of sound absorber is significance to architecture acoustic and noise control.In this paper,mode,distortion,sound pressure level distributing and optimization of sound absorber on the wall are studied by the finite element program ANSYS under sound wave, and sound absorber attach to the lowest price satisfed with acoustic require.Finally,the choice and disposal of sound absorber of medium-sized council chamber are studied.First of all, the numerical modeling of sound absorber model on the wall...
