How to Model Piezoelectric Devices as Both Transmitters and Receivers
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.
Simulating Nonlinear Sound Propagation in an Acoustic Horn
The Westervelt model enables you to perform complex acoustics analyses, such as modeling the propagation of nonlinear acoustic waves generated by an exponential horn.
Seeing Through Solids: Discovery and Applications of Photoacoustics
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?
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
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
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?
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
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.
