Is That a Ghost? Vibroacoustic Explanations for False Poltergeists
Creepy sounds are often misinterpreted as paranormal activity, when in fact, they can be explained with vibroacoustics, mechanical resonance, and attenuating sound.
Evaluating the Effect of Shell Thickness on Muffler Performance
Guest blogger Linus Fagerberg from Lightness by Design follows up a previous post with a discussion of one design consideration for the radiated sound in a muffler design: shell thickness.
Predicting the Sound Emission of a Muffler Design via Simulation
Cars with subpar mufflers are annoyingly loud. Guest blogger Linus Fagerberg from Lightness by Design discusses a novel, simulation-based approach to predict noise generation in muffler designs.
Using Simulation to Study Ultrasound Focusing for Clinical Applications
Guest blogger Thomas Clavet of EMC3 Consulting discusses the simulation of ultrasound focusing via phased array and geometrically focused probe designs for clinical uses.
Analyzing the Acoustics in a Simplified Particulate Filter Model
A diesel particulate filter catches exhaust emissions in some automotive systems. It’s important to study the acoustic properties of these filters, as they can affect mufflers and other parts.
Efficiently Analyze Acoustic Streaming with Multiphysics Modeling
Acoustic streaming is when sound waves are used to generate steady fluid motion. You can use multiphysics modeling for an efficiency way to analyze this phenomenon.
