🎶🔊 COMSOL Tutorial: Acoustic Impedance of Porous Material Using JCA Model 🧱🌍
In this COMSOL tutorial, we’ll calculate the acoustic impedance and sound absorption of a porous material using the Johnson-Champoux-Allard (JCA) model. You’ll also learn how to plot results with two y-axes for better data visualization.
What you'll learn:
✅ Calculate acoustic impedance and sound absorption with the JCA model
✅ Plot results on two y-axes for enhanced data analysis
✅ Validate the results with the open-access article
✅ Understand how the JCA model applies to porous materials
Results are validated by the following article:
