Using Transfer-Matrix Computation to Analyze Wax Guard Acoustics

January 28, 2020

The wax guard is an important part of a hearing aid, as it can improve the functionality and overall lifespan. We feature an acoustics model of a wax guard based on an actual industry example.

Optimizing Microspeaker Designs Using Simulation

January 7, 2020

From watches to laptops, microspeakers are found in devices we use everyday. In this blog post, learn how simulation can help optimize microspeakers and improve sound quality.

Analyzing the Sound Pressure Level of Headphones on Ears

December 19, 2019

Designing headphones presents a unique challenge: Unlike with loudspeakers, you can’t measure the sensitivity using a free-field setup due to the speaker’s closeness to the ear.

Modeling of NDT Methods Using COMSOL Multiphysics®

December 17, 2019

Active thermography, active ultrasonic, guided waves, acoustic emissions, and eddy current testing: 5 examples of how nondestructive testing (NDT) methods can benefit from multiphysics modeling.

Analyzing the Acoustics of a Head and Torso Simulator

September 6, 2019

Acoustics engineers designing hearing aids, cellphones, and headphones can perform standardized measurements faster and cheaper with simulation, as shown in this example.

How to Use Solver Suggestions in Acoustics Modeling

August 30, 2019

When you model large, industry-scale acoustics, ever find it challenging to efficiently solve the problem with the hardware at hand? Enter the solver suggestions in COMSOL Multiphysics®.

Samsung Amps Up Loudspeaker Designs with Simulation

July 29, 2019

Some organizations reach success and then shift the goal post. Take Samsung, for instance: Although they lead the market for televisions and smartphones, they set their eyes on another goal…

How to Automate Meshing in Frequency Bands for Acoustic Simulations

June 26, 2019

There is a large frequency range involved in acoustics phenomena, which means that modeling acoustics problems requires meshing a large wavelength range. COMSOL® offers an efficient way to do so.
