Mastering COMSOL: sound absorption coefficient BIiot Allard model

This video is about sound absorption coefficient of a porous material with Biot Allard model. This model is poroelastic and is more accurate than JCA. This video is about the absorption coefficient of a porous material with Biot Allard model. This model is poroelastic and is more accurate than JCA. poroelastic waves and pressure acoustics are coupled.
