The human ear consists of three portions—the external ear or concha; the middle ear or tympanum; and the internal ear or labyrinth. Specific physical stimulus for the organ of hearing consists of simple sound waves that unite sometimes as musical sound waves and sometimes as sound waves of noise. These sound waves act as stimuli upon the peripheral termination of the auditory nerve. This chapter focuses on auditory perception. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
