What is OAEs test ??
00:02
Otoacoustic emissions (OAEs) are sounds of cochlear origin, which can be recorded by a microphone fitted into the ear canal. They are caused by the motion of the cochlea's sensory hair cells, as they energetically respond to auditory stimulation.

OAEs provide a simple, efficient and non-invasive objective indicator of healthy cochlear function, and OAE screening is widely used in universal new-born hearing screening programs.

Screening OAEs
00:31
Most newborns are screened for hearing loss, and many hospitals use a 2-stage protocol in which all infants are screened first with otoacoustic emissions
00:40
In this protocol, no additional testing is done for those passing the OAE screening, but infants failing the OAE are also screened with automated auditory brainstem response (A-ABR)

As part of the audiological diagnostic test battery, OAEs can contribute to differential audiological diagnosis, they can be used to monitor the effects of treatment, and they can be helpful in the selection of hearing aids and of surgical options.

Screening Otoacoustic emission
01:08
Otoacoustic emission (OAE) tests are currently used to screen newborns for congenital hearing loss in many Universal Newborn Hearing Screening programs.
01:16
However, there are concerns about high referral and false-positive rates. Various protocols have been used to address this problem.
01:24
How do we do the test:
01:26
The child is not required to sleep during this test. However, for this test, your child, and everyone in the room, must be able to sit still and be very quiet.
01:36
Soft foam or rubber tips are placed in your child’s ear. Your child will hear soft sounds through the soft foam or rubber tips. A computer will record quiet echoes from the ear.
01:47
How long is the test??
01:49
The screening Otoacoustic emission test should only take a few minutes.
