Frequency discrimination depends on basilar membrane displacement separation

Evidence

Whether or not two components that are of similar amplitude and close together in frequency can be discriminated depends on the extent to which the basilar membrane displacements, due to each of the two components, are clearly separated. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 573
