| otoacoustic emissions, spontaneous | Sinusoidal tones originating in the cochlea. These faint sounds, with levels between 10-30 decibels, are usually not recognised by the persons having them.

The clinical significance of having or not having spontaneous otoacoustic emissions is unclear; however, some association between tinnitus and the spontaneous emissions has been reported.
