Modeling Acoustical Properties of Porous Media in COMSOL®

January 14, 2021

A guest blogger from the University of Sheffield introduces the Johnson–Champoux–Allard–Lafarge (JCAL) model for analyzing acoustical properties of porous media.

Keynote Video: Rapid Prototyping for Sonar Systems

December 15, 2020

Engineers at Northrop Grumman follow a 4-part rapid prototyping design phase: Design, manufacturing a prototype, testing and design verification, and manufacturing of the final design.

Modeling Sound Transmission Loss Through a Concrete Wall

October 7, 2020

The sound loss transmission (STL) through a building component is the logarithmic ratio between the total incident power on the structure relative to the total transmitted power.

What Is the Best Way to Analyze Fuel Tank Vibration?

August 4, 2020

In a traditional approach for modeling a fuel tank, the fluid mass is dispersed through the tank’s wetted surface. A multiphysics method specifically models the acoustic pressure in the fluid.

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.
