place theory

the theory that (a) sounds of different frequencies stimulate different places along the basilar membrane and (b) pitch is coded by the place of maximal stimulation. The first proposition is strongly supported by experimental evidence and stems from the fact that the mammalian auditory system shows tonotopic organization. The second hypothesis remains controversial. See Helmholtz theory. Compare periodicity theory.
