Center for Acoustics and Vibration


About Us

Gary Koopmann and Weicheng Chen

History

Penn State's Center for Acoustics and Vibration was founded by Dr. Gary H. Koopmann in 1989. The CAV is a College of Engineering Center, meant to:

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

Dr. Koopmann, with the help of leaders of the CAV's technical groups, brought together Penn State's acoustics and vibrations community - faculty and students alike - to participate in periodic group meetings each semester. Dr. Koopmann and his team also reached out to many corporate sponsors, whose membership fees helped CAV grow, and allowed us to hold yearly Spring Workshops, along with periodic CAV-sponsored short courses and conferences. Dr. Weicheng Chen was also critical to the success of the CAV, directing several of the CAV labs, and providing technical support, advice, and encouragement for students, faculty, and visiting faculty and scholars.

Through the years, the CAV laboratories have gone through a series of transformations to keep abreast of research trends. CAV labs include a sound transmission loss chamber, an anechoic chamber that accommodates jet noise research complete with a forward flight feature, a library and conference room, a well equipped structural vibrations laboratory, and ample room for graduate students in a variety of disciplines.

The CAV also initiated liaisons with international educational institutions, such as ISVR (U.K.), DLR (Germany), CIRA (Italy), and Insa de Lyon (France). Faculty and students from our international liaisons attend our Spring workshops, and visit the CAV for a semester or two to collaborate with Penn State faculty in their research.

Recent Developments

Following Dr. Koopmann's retirement in 2009, Dr. George Lesieutre assumed direction of the CAV, assisted by Dr. Stephen Hambric. George and Steve continue to lead the CAV forward following the principles established by Gary and Chen. To learn more about the CAV, please browse this website, or contact George at: gal4@psu.edu or Steve at: sah19@psu.edu

In recent years, the CAV's group of International Liaisons has grown to 8 organizations, and our corporate sponsors have also grown significantly. We have implemented a student thesis database where you can search for and access PDFs of theses in the areas of vibration and acoustics.

Karen Thal, our longtime CAV coordinator retired last Spring. Our new coordinator is Erin Ammerman. You can reach Erin at exa7@psu.edu, or at (814) 865-6364. Erin's office is in the Graduate Program in Acoustics area on the 2nd floor of the Applied Science Building.
