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).

Acoustic Topology Optimization with Thermoviscous Losses

February 28, 2018

A guest blogger from GN Hearing discusses including thermoviscous losses in the topology optimization of microacoustic devices, such as hearing aids, mobile phones, and metamaterial geometries.

Analyzing the Viscous and Thermal Damping of a MEMS Micromirror

January 29, 2018

Micromirrors are efficient and inexpensive. Here, we go over 2 types of analyses for a MEMS micromirror design, frequency-domain and transient, using the COMSOL® software.

How to Use Dispersion Curves to Analyze Fluid-Filled Pipes

November 8, 2017

Modeling a fluid-filled pipe is both a time-consuming and computationally expensive process, but there’s a way to streamline the process: a guided wave propagation approach via dispersion curves.

Keynote Video: Using Simulation to Develop Reliable Audio Transducers

November 1, 2017

An engineer from a loudspeaker company discusses using simulation to design a component that can handle fatigue, environmental conditions, and user wear and tear. Watch the presentation.

Is That a Ghost? Vibroacoustic Explanations for False Poltergeists

October 31, 2017

Creepy sounds are often misinterpreted as paranormal activity, when in fact, they can be explained with vibroacoustics, mechanical resonance, and attenuating sound.
