Study on the Optimization of Absorption Baffle with Coating Material

Abstract:

The absorption baffle making of viscoelastic structure with varying material can decrease effectively the sound reflection on the considerable bandwidth of sound-absorbing frequencies. In order to design the varying sectional cylindrical cavity which has better absorption result in more wide bandwidth, the mathematical model of the perforated ratio and optimization algorithm based on the genetic algorithm was designed. The simulation results based on the different rubber materials reveal that the selection of the shape of the cavity depends on the material characteristic. And the result from the optimization algorithm can be regarded as the effective referenced data.
