Dan Russell, a professor of Applied Physics at Ketting University, created this site to provide students animated images of sounds and vibrations produced by instruments such as loudspeakers and guitars. The site is divided into three sections, which include: "Acoustics I: Sounds and Sources," "Acoustics II: Sound and Vibration," and "Other Wave Phenomena (not acoustics, but still waves)." This site will surely be of assistance to those struggling with the intangible realities of wave phenomena.
