One just-noticeable pitch step shifts excitation across about six inner hair cells

Evidence

This frequency resolution is very high. Remembering that about 3600 inner haircells extend in a row between the helicotrema and the oval window with a distance of 9 J.lm from one to the next, we can estimate that one step in frequency corresponds to a shift of the excitation over a distance of 6 inner haircells. — Professor Dr.-Ing.
