Center for Acoustics and Vibration


Research in acoustics and vibration is one of Penn State's enduring strengths. The steady growth of research in acoustics and vibration in recent years establishes the Penn State program as the largest and most respected of its kind at a major research university. The Center for Acoustics and Vibration (CAV), housed in the Penn State College of Engineering, ensures the continued excellence of acoustics and vibration research in the new millennium.

The CAV has three missions:

  • to strengthen basic and applied research in related engineering areas;
  • to foster graduate education in acoustics and vibration engineering; and
  • to provide a base for technology transfer to industry.

The center consists of faculty, graduate students, and staff in nine laboratories throughout the College of Engineering. These laboratories perform both disciplinary and cross-disciplinary research in areas related to acoustics and vibration. Areas of research activity include: active control, adaptive structures, flow-induced noise, structural health monitoring, propagation and radiation, rotorcraft acoustics and dynamics, structural vibration and acoustics, and underwater acoustics.

News and Upcoming Events

Please welcome these new CAV sponsors:

  • Corporate sponsor: ITT, Mark Downing
  • Corporate sponsor: Carrier, John Wang
  • Corporate sponsor: K-Flex, Tony Ribaudo

This year’s CAV Spring workshop will be held 5-6 May 2015. Please look through our preliminary workshop agenda. Last year's workshop was attended by over 50 corporate sponsors, government liaisons, and international liaisons, as well as over 60 Penn State faculty and students. This year's short course immediately follows the workshop on 7 May, and will be taught by Bob Randall of the University of New South Wales in Australia. Bob will teach us about Cepstrum Analysis of Machinery Vibration and Structural Health. Please contact us if you would like to attend the workshop and the short course. We are holding a block of rooms at a reduced rate at the Nittany Lion Inn, so mention the CAV workshop when making your reservations.

We are excited to announce a searchable database of Penn State PhD and MS theses in Acoustics and Vibration is now available to our members. You can find links to PDFs of most of the theses in the database. We will continue to add other theses as students graduate.
