Andrew Barnard is a Senior Research Assistant at the Structural Acoustics Department at the Applied Research Laboratory at Penn State as well as a Doctoral candidate in the Graduate Program for Acoustics. Andrew is well versed in many areas of acoustics and vibrations, most recently receiving national and regional media attention for his work relating to crowd noise measurements in Beaver Stadium. This work was presented at the joint ASA/INCE conference in Baltimore, MD, on April 19, 2010. Subsequent press inquiries resulted in several media articles listed here:

· The Philadelphia Inquirer - A Lion's Roar: Penn State's Home-Field Advantage

· WTAJ TV video - On game day Beaver Stadium is Rockin'

· Penn State Live - Engineers measure crowd noise at Iowa-Penn State game

To see and listen to examples of our crowd noise measurements see the crowd noise section below.

Please feel free to contact Andrew to discuss your acoustics, noise, and vibration needs or to discuss opportunities available at Penn State's Graduate Program in Acoustics.

Research Interests

My research interests include most areas of acoustics, noise control, and vibration. Listed here are a subset of my primary research interests:

·         Sound and vibration data acquisition and signal processing

·         Matlab and LabVIEW software tools development for acoustics and vibrations

·         Community noise including crowd noise measurement and analysis

·         Outdoor sound propagation

·         Acoustics and vibration testing including modal analysis, signature analysis, acoustic holography, acoustic intensity, sound power, and community noise.

·         Acoustic material characterization

·         Architectural acoustics/room acoustics

·         Advanced loudspeaker array technology

Courses Taught

Currently I do not teach courses. I have previously team-taught ACS 402: Introduction to Acoustics.

Crowd Noise

Here are some samples of the data we collect at PSU football games. There are four example sound files and an animation that shows the crowd noise distributed around the stadium for the 2009 PSU-Iowa game. The animation was created by another PSU Acoustics student, Ryan terMeulen. You must have Windows Media Player to play the animation.

· Famous “We Are Penn State” chant

· Opening Kickoff

· Iowa 3^rd down resulting in a PSU interception

· PSU touchdown
