This systematic relationship between peak displacement and cochlear location serves as the linchpin of the "place" model of spectral representation and of auditory theory in general. In recent years this "classic" place model has come under increasing scrutiny in light of experimental observations demonstrating that this spatial organization of excitatory activity is generally discernible only under a restricted set of conditions in the auditory periphery, thus calling into question its ability to subserve frequency coding at sound pressure levels typical of speech communication and musical performance.
