OAE means otoacoustic emission, the name for sounds produced by the cochlea. These sounds can be used to test the function of the cochlea (especially hair cell function) and other parts of the ear including the auditory nerve.

Otoacoustic emission hearing tests are usually performed in newborns to detect deafness. The test can partially estimate hearing sensitivity and test for functional hearing loss. Functional hearing loss is also sometimes referred to as inorganic hearing loss and is a condition where you have symptoms or behaviors of hearing loss but in fact, there is nothing wrong with your hearing.

Some sources may refer to this as a listened hearing defect, but this is probably not entirely correct as it means that someone is “fecking” it and this type of hearing loss has many origins that Are not always under the control of a person.

Otacoustic emission hearing tests are typically used in combination with ABR (Auditory Brainstem Response) hearing tests or other hearing tests.

How the Test is Performed

The otoacoustic emission hearing test is not painful and many children sleep right through it. Small probes are placed in the ear. One distributes the sound and the other is the microphone. If the cochlea is functioning properly it should resonate in response to sound. There are four types of sounds that produce cochlea:

  • Spontaneous acoustic emission – The cochlea produces these sounds spontaneously (not in response to any other sound). These occur only in about 40–50 percent of people with normal hearing.
  • Transient otoacoustic emission – produced in response to another sound of short duration (transient). Usually, click or tone-burst. These are commonly used to evaluate hearing in infants.
  • Distortion product otoacoustic emission – produced in response to two simultaneous tones of different frequencies. These are particularly useful in quickly detecting damage to the cochlea (eg damage to the cochlea by ototoxicity or noise-induced damage).
  • Constant – frequency otoacoustic emission – produced in response to a constant tone. These are generally not used in the clinical setting.

Some conditions can cause the absence of OAE. These include ulcers, external otitis (eg swimmer’s ear), stenosis, or abnormal middle ear pressure, a perforated eardrum, otosclerosis, cholesteatoma.

Accuracy of Results

The OAE test cannot definitively diagnose hearing loss or deafness. If you fail the OAE test, you will need further hearing tests to determine if there is a hearing loss.

Sometimes the OAE test is incorrect because an infant is fussy during the test and sometimes infants have fluid in the ear or other conditions that can cause them to fail the test, even if they have no permanent hearing Do not harm Other factors that may cause the OAE test to fail or go wrong include:

  • Bad sealing around the ear probe
  • Ear wax blockage, especially if it prevents getting a good seal around the ear probe
  • Debris or foreign objects in the ear canal
  • An uncooperative patient

How the Otoacoustic Emissions Is Done 

A little headphone, or test, is put in your ear. The test places sound into your ear and measures the sounds that return. You don’t have to do or say anything during the test. The individual doing the test can see the outcomes on the screen.

OAE represents otoacoustic emissions, the name for the sounds created by the cochlea. These sounds can be utilized to test the capacity of the cochlea (explicitly hair cell work) and different pieces of the ear, including the sound-related nerve.

applies for Otoacoustic Emissions

Otoacoustic Emissions Hearing tests are normally performed on infants to recognize deafness. The test can likewise halfway gauge hearing affectability and test for useful hearing loss. Practical hearing loss is additionally once in a while alluded to as non-natural hearing misfortune and is where you have indications or practices of hearing loss yet there is nothing, in reality, amiss with your hearing.

A few sources may allude to this as pretended hearing misfortune yet that is likely not totally precise as this infers somebody seems to be “faking it” and this sort of hearing misfortune has various roots that are not generally inside a people control. 

Otoacoustic Emissions Hearing tests are generally utilized related to the ABR (Auditory Brainstem Response) hearing test or other hearing tests.
