**r4.02.01** Finite elements in acoustics
==========================================

**Summary:**

This document describes in stationary linear acoustics at low frequency in a bounded environment the equations used, the variational formulations that result from them as well as the corresponding translation into isoparametric finite elements using a usual formulation with an unknown :math:`p` (sound pressure). This document corresponds to PHENOMENE =' ACOUSTIQUE '.
