Computing the HRTF of a Scanned Geometry of a Human Head

July 14, 2020

Designing cochlear implants, hearing aids, headphones, and other audio devices requires precise measurements of the head-related transfer function (HRTF). Simulation and geometry import can help.

Modeling an Ear Canal’s Acoustics to Optimize In-Ear Audio Products

July 7, 2020

Ever notice an echo-like sound when wearing headphones or earbuds? Called the occlusion effect, this phenomenon can be studied using acoustics modeling to design better in-ear audio products.

Introduction to the Elastic Waves, Time Explicit Interface

May 28, 2020

From nondestructive testing to seismic wave propagation in soil and rock, there are many application areas that involve the propagation of elastic waves in solids and vibrations in structures.

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.
