Pressure distribution of the Helmholtz resonant mode.

This paper aims to demonstrate the simulation of photoacoustic signals using FEM software. The Acoustics Module of the software COMSOL Multiphysics is used to calculate the response of a differential Helmholtz resonator cell. In a second part a preliminary result obtained with the Thermoacoustics interface is also presented.
