Otoacoustic Emission
Contrary to popular belief, the cochlea is capable of not only receiving sounds, but also of sound emission. Otoacoustic emissions are sounds that emanate from the cochlea. These are typically low volume and low frequency such that they cannot be heard by even the patient. However, on rare occasions, the emitted sounds will be loud enough to be heard by an observer.
