Acoustics and Vibration Animations
Professor of Acoustics
Director of Distance Education
Graduate Program in Acoustics
The links below contain animations illustrating acoustics and vibration, waves and oscillation concepts. I started using Mathematica to create animations to help me understand and visualize certain acoustics and vibration phenomena in 1992 while I was a Ph.D. student in the Graduate Program in Acoustics at Penn State. For the next 16 years (1995-2011) I was a physics professor at Kettering University and continued creating animations and using them as educational tools for the courses I was teaching about waves and acoustics. Sometime around 1998 or so I began writing webpages and adding them to this online collection. Now that I'm back at Penn State, teaching graduate level acoustics, I'm continuing to add to my collection of animations. My intent has always been to create physically and mathematically correct animations, accompanied by explanatory text, that illustrate complicated phenomena involving waves and vibration in a manner that aids student understanding. I hope you find these animations useful.

I am in the process of attempting to bring all of the pages on this site into compliance with current HTML5, CSS3, and W3C Web Accessibility standards. The bullet symbols used in the lists below identify pages as
- (open circle) still needs to be updated
- (filled disk) updated to HTML5 and CSS3.
As far as I can tell most of the updated pages work correctly with Safari v6, Google Chrome v24, Maxthon 4, and Explorer v10. Occasionally I discover some layout and style problems with Firefox. Many of the pages below include math equations formatted using MathML, and I have learned that Chrome versions after 24 have removed support for MathML, and Internet Explorer requires the MathPlayer plugin in order to render MathML equations properly.
Please let me know if you find page errors or pages that don't load correctly. Thanks!
