These faint sounds, with levels between 10-30 decibels, are usually not recognized by the persons having them. However, the emissions can be recorded using sensitive microphones placed in the ear canals. 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. |
