Abstract

The objective of this study to decrease the sound at outside of a bowl shaped solid, Point source is being used for generate the sound. Poro-acoustics and Acoustic structure interaction modules have been used for simulation, the Frequency Domain study is used to compute the response of a linear or linearized model subjected to harmonic excitation for one or several frequencies. Three major scenarios have been considered to analyze the sound at inside and outside of a bowl.;1. Change in the design of a bowl 2. Change the parameters of inlet & outlet radius 3. Change the material of a Lid.
