Mahavir ENT Hospital offers Bera hearing test in Rajasthan. When a auditory stimulus (sound) is presented to the ear, an electrical potential is evoked in the cochlea in response to the sound stimulus and this electrical output called ‘action potential’ traverses through the auditory pathway to reach the higher areas in the brain where it is processed and the meaning pertaining to the sound interpreted. BERA 1. (1✔) The procedure is also called Auditory Brainstem Response (ABR), Brainstem Auditory Evoked Potential (BAEP), Brainstem Auditory Evoked Response (BAER) and Evoked Response Audiometry (ERA). In its most severe form Guillain-Barre syndrome is a medical emergency. These vibrations are conducted by three small bones in the middle ear, the malleus, incus and stapes to the inner ear. It is a very reliable but time consuming test to objectively evaluate the hearing threshold of an adult or child across all frequencies except for the low frequencies.The term objective signifies that the patient does not have to subjectively respond to  the sound stimuli and convey whether the patient is hearing the sound or not which is required in most hearing tests. In rare cases, the neural pathways may not conduct sound normally. (Acoustic schwannoma). Uses of BERA: 1. Monitoring of central and peripheral nervous system during surgical procedures like treatment of facial palsy or. These links to other websites do not imply a recommendation for all the content found on these sites. In medical parlance this test is an auditory evoked potential test. These waveforms are recorded by the electrodes that are placed over the scalp at various places as follows: Non-inverting electrode over the vertex of the head, which is the most prominent point at the back of the head. So these tests should be included in the test battery for the screening of patients complaining of tinnitus even with normal hearing. It is an effective screening tool for evaluating cases of deafness due to retrocochlear pathology i.e. Most adults who get hearing tests are asked to wear earphones and listen to short tones that are played at different volumes and pitches into one ear at a time. The test procedure and the interpretation of the results are typically done by an audiologist.(3✔). BERA. I am often confused to detect whether the sound is comming or not. The ABR is also used if your symptoms might be due to hearing loss in the brain or in a brain pathway. The Brainstem Evoked Response Audiometry (BERA)Test: – also called the ABR test or the BSER test is an objective test of hearing that is traditionally used for testing the structural and functional integrity of the auditory pathway from the inner ear to the midbrain. BERA Test, Hearing Testing, Hearing Aid Accessories, Hearing Aids, Definite Hearing Center, Doctors. Follow @Medindia Audiometry or the hearing test helps to determine the ability of a person to hear various sounds and consequently identify the location of damage in a person with diminished hearing sensitivity.

Weakness and tingling in your extremities are usually the first symptoms.These sensations can quickly spread, eventually paralyzing your whole body. Objectives: The brainstem evoked response audiometry (BERA) is an objective neurophysiological method for the evaluation of the hearing threshold and diagnosing retrocochlear lesions. Disclaimer. What is Brainstem Evoked Response Audiometry (BERA)? Complete Solution. 3. The test checks hearing pathway from the ear to the brain. It is usually done using a click sound by which the subject’s average hearing threshold across all frequencies is evaluated.The BERA test is also done to identify the site of lesion  i.e., the anatomical region in the brain where there is a damage in the auditory pathway inside  the brain in  patients suffering from vertigo / deafness / tinnitus. Screening for hearing loss in newborns, infants and other young children. Since a big portion of the neural pathway that connects the balance organ situated deep inside the ear to the higher levels in the brain also traverses along the same pathway as the auditory pathway, BERA though primarily a test of the hearing system, is a very important test for patients suffering from balance disorders like vertigo / imbalance. Khar West. CHIRP BERA which is a very sophisticated form of BERA test is also possible in Vertigo and Deafness Clinic.

BAER (Brainstem Auditory Evoked Response) testing is usually performed if your infant has failed their otoacoustic emissions (OAE) testing unless your child was born prematurely. BERA (Brainstem Evoked Response Audiometry) is also mentioned as Auditory Brainstem Responses is an electro-physiological test procedure to measure the responses of brain waves stimulated by a clicking sound to identify the central auditory or hearing pathways of the brainstem. Evaluation of hearing loss due to retro-cochlear pathology (lesion beyond the cochlea), like acoustic neuroma or acoustic schwannoma. The test is used with children or others who cannot complete a typical hearing screening. 6 months or older, the ABR might be done with sedation.
