This course introduces acoustics and psychoacoustics at a freshman level. Acoustics is the physics that is responsible for creating (mostly) audible phenomena. Psychoacoustics is the physiology, psychology and cognition of humans and animals which leads to a perception of acoustical phenomena. The course discusses oscillation, wave physics, space-time-frequency relationships interference, musical acoustics, room acoustics as well as perception of pitches, loudness, timbre, tuning, masking, and spatial hearing.
