Intro from Consciousness: Epiphony by Jackson May

"The term sound can denote the physical phenomenon of vibrations that set into motion longitudinal waves of compression and rarefaction propagated through molecular structures such as gas liquids, and solids; the physiological phenomenon that stimulates the sense of hearing; or the psychophysical perception of sound stimuli."

"Sound begins when an object vibrates and sets into motion molecules in the air closest to it. These molecules pass on energy to adjacent molecules, starting a reaction-a sound wave-which is much like the waves that result when a stone is dropped in a pool. The transfer of momentum from one displaced molecule to the next propagates the original vibrations longitudinally from the vibrating object to the hearer. What makes this reaction possible is air or more precise, a molecular medium with the property of elasticity. Elasticity is the phenomenon in which a displaced molecule tends to pull back to its original position after its initial momentum has caused it to displace nearby molecules."
