Which is better ABR or OAE?

ABR tests typically require more time than OAE tests and tend to be more expensive. ABRs are less susceptible to the status of the middle ear, and are more sensitive than OAEs to disorders such as auditory neuropathy or other neural problems.

What type of hearing measure is best for testing newborns?

Auditory brainstem response (ABR) testing is the best test available for newborns and infants up to 6 months of age that can provide information about the softest level of sound the ear can hear. Sounds are played to the baby’s ears and band-aid like electrodes are placed on the baby’s head to detect responses.

Why using both OAE and ABR is important in ensuring correct diagnosis of hearing loss in babies?

We screened all of the babies with both technologies. Then we followed those children who had a refer result on either screen. The advantage of using both OAE and ABR is you can determine not only that the child did not pass the screening, but why they did not pass. This is a mini version of the crosscheck principle.

What is the difference between OAE and Bera?

Brain Evoked Response Auditory (BERA) is a hearing examination performed on children aged 1 to 3 years. Meanwhile, for children with a smaller age, Oto Acoustic Emission (OAE) examination can be carried out.

What are the limitations of ABR?

The limit between audiograms with and without reproducible ABR passed roughly through 40-50 dB HL at 500 Hz and 80-90 dB HL at 1000 Hz.

What is OAE hearing test?

The OAE (Otoacoustic Emissions) test checks part of the inner ear’s response to sound. The test is mostly done on infants and children who may not be able to respond to behavioral hearing tests because of their age.

Can ABR hearing test be wrong?

Although the test is relatively accurate, it sometimes fails to detect hearing impairments. This is known as a “false negative” test result.

How accurate is ABR testing?

Auditory Brainstem Response (ABR) For this high-risk population, the sensitivity and specificity was 98% and 96% when the ABR screening threshold was set at 40 dB HL and 100% and 91% when the ABR screening threshold level was set at 30 dB HL (see slide #19).

Why is OAE test important?

Otoacoustic emissions (OAE) screening can help to detect sensorineural hearing loss occurring in the cochlea. It can also call attention to hearing disorders affecting the pathway to the inner ear.

Are ABR and Bera same?

The BERA test measures the reaction of the parts of a child’s nervous system that affect hearing. The ABR test measures the auditory nerve’s response to sounds.

Is OAE a hearing test?
