🔊📉 Ansys Tutorial: Sound Absorption Coefficient Using the JCA Model 📐📘
In this Ansys tutorial, you'll learn how to calculate the sound absorption coefficient using the Johnson-Champoux-Allard (JCA) model.
We’ll be using:
🧰 Ansys Workbench with the Harmonic Acoustics system
🛠️ SpaceClaim to create the impedance tube geometry
📄 Material parameters from an academic paper (5 required for the JCA model)
This tutorial is ideal for anyone working on acoustic materials, porous modeling, or interested in sound absorption analysis.
