title: Our present experience on spontaneous cochlear emissions.
abstract: Spontaneous otoacoustic emissions (SOAEs) consist of one or several sinusoid-like signals. Small broadening of the spectra of SOAEs, are likely due only to some small oscillations and shifts of their center frequency. Presence of a detectable SOAE seems to be attributable to hearing losses of minor severity associated with abnormal synchronization. A part from some amplitude variations, SOAEs, remain consistently the same over prolonged periods of time and for this reason have been called finger-print-like in the literature. They seem to reflect physiological and exposure-related shifts in tonal projection. SOAEs are one of the proverbial key holes through which we can have a glimpse of what is happening into the cochlea.
