Music Acoustics
Music acoustics is a multidisciplinary field that combines knowledge from physics, psychophysics, physiology, and signal processing among other disciplines. As a branch of acoustics, it is concerned with researching and describing the physics of music, how sounds are employed to make music. Examples of areas of study are the function human voice (the physics of speech), computer analysis, and in the clinical.
