Have You Heard About the Cocktail Party Problem?

November 7, 2017

You’re at a party with loud music and a ton of people. Despite the noise, you are able to chat with a friend. How is it that you can differentiate his or her voice from all the sounds around you?

Keynote Video: Using Simulation to Develop Reliable Audio Transducers

November 1, 2017

An engineer from a loudspeaker company discusses using simulation to design a component that can handle fatigue, environmental conditions, and user wear and tear. Watch the presentation.

Is That a Ghost? Vibroacoustic Explanations for False Poltergeists

October 31, 2017

Creepy sounds are often misinterpreted as paranormal activity, when in fact, they can be explained with vibroacoustics, mechanical resonance, and attenuating sound.
