OAE

The otoacoustic emission (OAE) test is an accurate, informative and time-saving tool which is simple to perform. It is considered that if OAE is recorded, an infant’s hearing is not impaired. In case OAE is not recorded, it is an indication to see an audiologist to perform the further examination of an infant.

Otoacoustic emission is the acoustic response which reflects the normal functioning of the auditory receptor. These are low-intensity sounds generated by cochlea which can be recorded in ear canal with the use of highly sensitive microphone. These sounds are the result of active mechanical processes running in the organ of Corti, namely in outer hair cells.

OAE is intended mostly for screening as it takes little time. It is very important also because the long-term immobility of an infant is sometimes impossible. Several types of this technique exist, but in practice the most often used ones are transient evoked otoacoustic emission (TEOAE) and distortion product otoacoustic emission (DPOAE).

ABR / BERA

When you use only OAE technique for screening, patients with normal cochlea function but with possible retrocochlear impairments (for example, with auditory neuropathy) drop out of sight. The ABR technique does not have such drawback.

The essence of this technique is the acquisition of the electrical potentials evoking in different structures of auditory system in response to auditory signal which defines its objectivity.

Auditory brainstem response (ABR) or brainstem evoked response audiometry (BERA) is widely used in audiology.

  • The advantages of this test:

ABR can be recorded in newborn from first hours of life including premature infants and newborns suffering from central nervous system diseases.

ABR acquisition is noninvasive (safe and harmless).

ABR acquisition provides objective information concerning the state of auditory pathways.

ABR characteristics are stable and do not depend on a patient’s state (whether she/he is awake or asleep, this sleep is natural or drug-induced).

  • Besides, ABR screening has the following advantages:

The stimulation frequency is increased up to 93 Hz, it allows making 8000 averagings per less than 2 minutes.

The test has several automatically calculated "Pass" criteria. As soon as these criteria are checked, the test is stopped automatically and "PASS" or "REFER" result is displayed on the screen.

To record ABR, the same OAE probe as for OAE acquisition is used.

During two-stage hearing screening, in case an infant did not pass OAE test, a doctor should make ABR test to specify the diagnosis.
