Previously, we introduced the theory behind thermoacoustics. Here, I will go deeper into modeling acoustics with the Thermoacoustic interface in COMSOL Multiphysics and show you some tips and tricks on how to do this.

When sound propagates in structures and geometries with small dimensions, the sound waves become attenuated because of thermal and viscous losses. More specifically, the losses occur in the acoustic thermal and viscous boundary layers near the walls. This is a known phenomenon that needs to be included when studying and simulating systems affected by these losses in order to model these systems correctly and to match measurements.
