To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.

By combining several Port boundary conditions, you can easily compute the transmission and insertion loss in exhaust and muffler systems. See more benefits of this feature for acoustics modeling.

It’s not just science fiction: Objects really can levitate. 1 way this is possible is by using sound waves to lift and suspend particles midair. Simulation can broaden the use of this technology.

Certain types of transducers can act as both transmitters and receivers. We demonstrate how to use 2 features for modeling this type of piezoelectric device.

The field of photoacoustics started with Alexander Graham Bell and some sunlight. Now, photoacoustic imaging is used for nearly anything involving generating images of opaque material samples.

Signals generated via photoacoustic spectroscopy are often weak and difficult to detect. Acoustic cells can be used to amplify the signal, but they need to be designed with sensitivity in mind.

A variety of use cases and a variety of physics: Piezoelectric transducer designs need to account for electric currents, pressure acoustics, stress-strain, and acoustic-structure interaction.

How do Archimedes, a gold crown, and a bathtub relate to acoustics modeling? Find out in this blog post on modeling fundamental sources in enclosed spaces that will have you shouting “eureka!”

The Westervelt model enables you to perform complex acoustics analyses, such as modeling the propagation of nonlinear acoustic waves generated by an exponential horn.

Engineers can design optimized loudspeaker arrays and other acoustics systems by analyzing a benchmark model of a Bessel panel system like the one featured in this blog post.
