Abstract
This proposed research uses COMSOL Multiphysics to investigate impedance tube-based parameter estimation strategies. The primary focus of this study is on acoustic and sound pressure properties, which have applications in material characterization and noise control strategies. Impedance tubes are critical tools for testing essential acoustic properties such as sound absorption, reflection, and transmission loss in order to produce materials with specific acoustic responses. These characteristics are critical for designing materials. To collect data on acoustic impedance, sound pressure levels, and other frequency-dependent properties across a variety of material types and thicknesses, we model an impedance tube setup in the COMSOL modelling environment. The simulations provide a controlled environment for investigating sound pressure distributions and acoustic wave interactions inside the tube. This provides insight into the relationship between the material's properties and its acoustic responses. To validate the process, the collected data is compared to analytical models. This comparison demonstrates the accuracy and dependability of this method for predicting acoustic properties of materials. This discovery expands the possibility for automated, non-destructive testing and material optimization in acoustic applications.
