Whether you're curious about why music sounds better in some rooms than in others or you want to learn how to derive the equations for the Doppler shift, tune in to this site from retired engineer Art Ludwig of Santa Barbara, California. Although short on graphics, the site is well stocked with informative text explaining the physics of sound for beginners and experts. The mathematically adept can learn how to work out the sound equations from a model of molecular motion. Or delve into image analysis, which is useful for evaluating the acoustics of a room. Math-free sections explore topics such as the fundamentals of sound and how we hear music.
