Introduction
The Acoustics Module is an optional package that extends the COMSOL Multiphysics® environment with customized interfaces and functionality optimized for the analysis of acoustics and vibration problems.
This module solves problems in the general areas of acoustics, acoustic-structure interaction, aeroacoustics (convected acoustics and flow-induced noise), thermoviscous acoustics, linear ultrasound, pressure and elastic waves in porous materials, vibrations, geometrical acoustics, pipe acoustics, nonlinear acoustics, and acoustic streaming. The physics interfaces included are fully multiphysics enabled, making it possible to couple them to any other physics interface in COMSOL Multiphysics. Explicit demonstrations of these capabilities are supplied with the product in a library (the Acoustics Module Application Library) of ready-to-run models and applications that make it quicker and easier to get introduced to discipline-specific problems. One example being a model of a loudspeaker involving both electromechanical and acoustic-structural couplings.
This chapter is an introduction to the capabilities of the Acoustics Module and gives a short introduction to the fundamentals of acoustics. A summary of the physics interfaces and where you can find documentation and model examples is also included. The last section is a brief overview with links to each chapter in this guide.
