The Physics of Sound
S06, S07 
Norman Derby
In this course, you will become acquainted with pressure vibrations in the air and with the various ways in which human beings turn these vibrations into the complex perceptions we call sound. For instance, what actually comes out of the tiny speaker of a small radio is really very different from what we hear in our heads—we are much more than simple microphones. By means of a large number of demonstrations, you will acquire direct experience with the physics of sound and vibration, musical phenomena (scales, beats, tuning, temperament, instrument design, construction, and performance), room acoustics, and human perceptual mechanisms.
