Comsol's Acoustics Module

Scientists and engineers interested in creating and measuring sound or acoustic waves will find new simulation capabilities in 'Acoustics Module' introduced by Swedish company Comsol (read about its partial differential equation solver, Femlab in our past posting). It is ideal for examining linear mechanical wave phenomena in structures and fluids. It is designed specifically for those who work with devices that generate, measure, and use acoustic waves. Users can model wave propagation in solids and stationary fluids, and can study aeroacoustics in moving fields.

Application areas include the audio industry, such as for loudspeaker design, whether as standalone speakers or those embedded into electronic appliances such as cell phones; for underwater object detection and characterisation; and far-field processing to predict radiation patterns and signal strength.

The module provides a variety of application modes, which offer tailored user interfaces loaded with predefined settings important for acoustics applications. Users create or import a geometry, fine-tune the physics settings, and solve the problem.

The modeling of acoustics-structure interaction is easily done within the Acoustics Module, particularly for applications such as the design of SONAR devices transducers for use in medical and non-destructive testing applications and noise and vibration. It also contains a specific interface for modeling aeroacoustics, especially for the control of aircraft engine noise, while making use of its general multiphysics ability provides further accuracy to classical acoustics.
