Modeling an Ear Canal’s Acoustics to Optimize In-Ear Audio Products
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
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
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
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
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®
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
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
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
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
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.
Introduction to Modeling Acoustic-Structure Interactions in COMSOL®
To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.
Frequency Response of Mechanical Systems
Read this blog post for a detailed look at damped mechanical systems, a guide to setting up frequency-response analyses in COMSOL®, and a discussion of how to interpret your results.
