Abstract

The main goal of this paper is to calculate the REFLECTIVITY INDEX and SCATTERING INDEX of incident acoustic plate waves from a SOUND ABSORBENT TILE. The simulations are performed using Comsol software and obtained results are plotted as a function of the frequency of incident wave. It should be noted that the acoustic absorbent tile consists of an array of close-packed cones which are placed on a simple plate. Additionally, the acoustic absorbent tile is made of metal loaded BUTYL RUBBER. The BUTYL RUBBER is loaded with aluminum and lead. By comparing obtained results with analytical and experimental reported results one can deduce that performed simulations with Comsol software are as reliable as expected. Moreover, it is shown that the absolute values of the SCATTERING INDEX and REFLECTIVITY INDEX of tile which is made of aluminum loaded BUTYL RUBBER are larger and hence this tile should be applied in experimental fabrication.
