Stereocilia located at positions 1 to 8 reveal only a slight decrease in relative force from 36 to 20%. The background noise level of about 20% is due to acoustical evoked vibrations of the AFM cantilever caused by the oscillating piezoelectric tube and liquid coupling. Absolute forces in Fig. 8A also show a fast decline from stereocilium 0 to 1.
