Brain scans illuminate emotional response to sound
Noisy gymnasiums, restaurants where conversations are nearly impossible and concert halls less than perfect for the music are all acoustical problems. Now Penn State acoustical engineers are using functional MRI to better understand room acoustics and the emotions they can cause.  View News Article (2015-11-17)

Seats Helped Ancient Greeks Hear From Back Row
As the ancient Greeks were placing the last few stones on the magnificent theater at Epidaurus in the fourth century B.C., they couldn't have known that they had unwittingly created a sophisticated acoustic filter. View News Article (2007-04-05)

New technology modifies music hall acoustics
A new technology that relies on a system of inflatable sound absorbers may help make any performance hall instantly convertible into a venue for music ranging from classical to hard rock. View News Article (2013-06-03)

Sound understanding of indoor acoustics could make hearing easier
An innovative technique that, for the first time, accurately measures exactly how sound behaves in 'real-world' situations is now under development-and could improve acoustics in buildings ranging from concert halls to railway stations. View News Article (2006-09-08)

An efficient method for solving sound propagation in range-dependent ocean waveguides was found
The coupled normal mode method is a powerful approach for solving range-dependent propagation problems in underwater acoustics.  View News Article (2012-04-10)

Acoustic Cloaking Device Hides Objects from Sound
Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated the world's first three-dimensional acoustic cloak. View News Article (2014-03-12)
