How Subtle Head Motions, Quiet Sounds Are Reported To The Brain
Published February 9, 2010, 9:10 am, redOrbit
The phrase "perk up your ears" made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain.When a sound is barely audible, extremely sensitive inner-ear "hair cells"—which are neurons equipped with tiny, sensory hairs on their surface—pump up the sound by their very motion and mechanically amplify it.
Built-in amps: How subtle head motions, quiet sounds are reported to the brain

Subtle head motions are amplified by inner-ear hair cells before the signal is reported to the brain, report Marine Biological Laboratory scientists and colleagues. In both the auditory and the vestibular systems, hair cell response is nonlinear: the lower the strength of the stimulus, the more the hair cell amplifies the signal.
