Sound is about much more than the ears. We hear with our brains, for it is our brains that make sense of sound. Making sense of sound is accomplished by a vast distributed and integrated system of cognition, sensation, and reward — and in this system, the brain-to-ear connections are just as pervasive and important as the ear-to-brain connections. Consequently, our life in sound shapes us deeply — as a musician or a speaker of two languages on the one hand, or as an aging adult or an individual with a language disorder on the other.
