Otoacoustic Emissions (OAEs)
Types of otoacoustic emissions
An Otoacoustic emission or OAE is a sound which is generated from within the inner ear. It’s a low-level sound emitted by the cochlea either spontaneously or evoked by an auditory stimulus and it specifically provide information related to the function of the outer hair cells also known as OHC. Broadly speaking, there are two types of otoacoustic emissions. One it is known as Spontaneous Otoacoustic Emissions or say SOAEs, which can occur without external stimulation, and Another is known as Evoked Otoacoustic Emissions
Otoacoustic Emissions (OAEs) are sounds given off by the inner ear when the cochlea is stimulated by a sound. When sound stimulates the cochlea the outer hair cells vibrate. The vibration produces a nearly inaudible sound back into the middle ear. The sound can be measured with a small probe inserted into the ear canal or say EOAEs, which require an evoking stimulus.
