Man is born with a psychophysical organism which registers sounds and responds to them somewhat like a resonator, which selects, amplifies and aids in the integration of auditory impressions. Our whole organism responds to sound involving the central and peripheral nervous system, all the muscles, all the internal organs, and especially the automatic nervous system with its endocrines, which furnish the triggers in the physical generation of emotion. Experiments from various sources have shown that sound acts physiologically on nervous control, circulation, digestion, metabolism, body temperature, posture and balance, hunger and thirst, and in general, the groundwork of pleasure and pain. The physical organism as a whole responds to sounds in specialized functions.
