Hearing two tones as separate requires separate basilar membrane peaks

Evidence

The point at which the two tones are heard as being separate as opposed to fused when the frequency difference is increased can be thought of as the point at which two peak displacements on the basilar membrane begin to emerge from a single maximum displacement on the membrane. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 577
