Seeing Through Solids: Discovery and Applications of Photoacoustics

August 30, 2018

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.

How Do Chladni Plates Make It Possible to Visualize Sound?

August 17, 2018

Is it possible to see sound? Find out for yourself in this blog post on the acoustics behind Chladni plates.

Analyzing a Loudspeaker Array with a Bessel Panel Benchmark Model

July 23, 2018

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.

How to Perform a Nonlinear Distortion Analysis of a Loudspeaker Driver

June 18, 2018

For a thorough and complete analysis of a loudspeaker driver design, acoustics engineers need to perform nonlinear time-domain studies in addition to frequency-domain studies.

What Is the Doppler Effect?

May 29, 2018

A siren passes by and you hear a change in pitch. A bug swims across a puddle, causing ripples on the surface. A star in the sky has a reddish hue. These are all examples of the Doppler effect.

Teaching Students About Acoustics Phenomena with Apps

April 27, 2018

Acoustics concepts and their underlying theories can be difficult for engineering students to visualize. For one university, simulation applications proved to be an effective teaching tool.

Finding Answers to the Tuning Fork Mystery with Simulation

April 13, 2018

If you strike a tuning fork and hold it against a tabletop, the peak frequency of the emitted sound doubles. Is there a physical explanation for this “tuning fork mystery”?

How to Use the Boundary Element Method in Acoustics Modeling

March 19, 2018

Learn advantages and strategies for using the boundary element method (BEM) for acoustics modeling. Plus, we go over a hybrid approach that combines BEM with the finite element method (FEM).
