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.
