What is ASSR hearing test?

What is ASSR hearing test?

Background: The auditory steady state response (ASSR) is an auditory evoked potential (AEP) that can be used to objectively estimate hearing sensitivity in individuals with normal hearing sensitivity and with various degrees and configurations of sensorineural hearing loss (SNHL).

What is the difference between ABR and BERA test?

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.

What is ABR and ASSR?

ASSR and ABR are both auditory evoked potentials. ASSR and ABR use acoustic stimuli delivered through inserts (preferably). ASSR is evoked using repeated sound stimuli presented at a high repetition rate, whereas ABR is evoked using brief sounds presented at a relatively low repetition rate.

What is the meaning of ASSR?

or A.S.S.R. Autonomous Soviet Socialist Republic.

Why Bera test is done?

Brainstem-evoked response audiometry (BERA) is a simple, noninvasive, objective test for early identification of hearing impairment in children and neonates. It can be used as a screening test and is useful in newborns, infants, and other difficult-to-test patients.

What is the full form of Bera?

Objectives: The brainstem evoked response audiometry (BERA) is an objective neurophysiological method for the evaluation of the hearing threshold and diagnosing retrocochlear lesions.

How is Bera done?

Electrodes will be placed on the patient’s head and behind the ear during the BERA test procedure. When the examination is done, the patient will be heard various sounds through headphones. This examination measures changes in brain electrical activity (EEG) in the provision of acoustic stimuli.

How accurate is BERA test?

In our study sensitivity & specificity of OAE 70\% and 61\% at 0 month and 70\% and 99\% at 3 month and BERA sensitivity and specificity at 3 month 90\% and 99\% and at 6 month 100\% and 99\% .

What does an ABR test measure?

The ABR (Auditory Brainstem Response) test can be used to detect hearing loss. It checks your child’s brain’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.

How is ASSR test done?

An auditory steady-state response (ASSR) is an electrophysiological response that is evoked by a periodically repeated (rapid) auditory stimulus. An ASSR typically uses frequency specific stimuli (0.5, 1, 2, 4 kHz) with the goal of creating an estimated audiogram.

Is BERA test painful?

Abnormalities that occur in the transmission of signals when the sound is heard indicates hearing loss. This examination has no risk of complications, is painless, and does not require special preparation for the BERA test.

What is the cost of BERA test?

A simple brainstem evoked response audiometry (BERA) test can identify cause of hearing problems. BERA test costs about Rs 1,000 approximately.
