On the Sensations of Tone (1870; English 1875) (Thoemmes Press - Classics in Psychology) (Vol 9)

The foundational work in physiological acoustics and the greatest single contribution to the psychology of audition. Helmholtz's description of the anatomy and physiology of the auditory system, his analysis of the nature of acoustic events, and his resonance theory of hearing paved the way for all later work in this field.
