Electrodes will be placed on the patient’s head and behind the ear during the BERA test procedure. IF he has any hearing loss, if, they will decide if … The measured recording is a series of six to seven vertex positive waves of which I through V are evaluated. I remember that in my first year, the statistics professor taught us that for linear regression your data would ideally be normally distributed, but if you have a larger amount of cases (n>40) this criterium becomes much less important. The test is also called a brainstem auditory evoked potentials (BAEP) or auditory brainstem response (ABR) test. These results illustrate the necessity to test children hearing even with the slightest suspicion by the parent or doctor of hearing loss. The BERA diagnostic procedure was applied in 184 children ranging from 1 to 12 years of age at Ahmadi Hospital in Kuwait.  |  BERA test makes it possible to estimate the rate of passage of the […] 2015 May;9(5):CC01-3. Whether the departure is significant is answered by statistical tests of normality such as the Jarque Bera Test and the Omnibus Test. The test statistic of the Jarque-Bera test is always a positive number and the further it is from zero, the more evidence that the sample data does not follow a normal distribution. Prerequisites for this test: However, if the BERA test results are declared abnormal, then the examination will continue with the estimation or prediction of the hearing threshold and hearing rehabilitation must be carried out as early as possible by using hearing aids. Would you like email updates of new search results? In the former case the whole input series of residuals is used. The test statistic of the Jarque-Bera test is always a positive number and if it’s far from zero, it indicates that the sample data do not have a normal distribution. An ABR test is often ordered if a newborn fails the hearing screening test given in the hospital shortly after birth, or for older children if there is a suspicion of hearing loss that was not confirmed through more conventional hearing tests. Out of the children with delayed speech, 63% had some level (mild-profound) of hearing loss which actually caused the delay in speech development; 37% had normal hearing, but inadequate verbal communication affected their language acquisition and speech development. The test statistic of the Jarque-Bera test is always a positive number and the further it is from zero, the more evidence that the sample data does not follow a normal distribution. Out of the children suspected for hearing loss, 42% actually had some level (mild-moderate) of hearing loss. Abnormalities that occur in the transmission of signals when the sound is heard indicates hearing loss. NOTE: This test only works for a large enough number of data samples (>2000). Head sensors and earphones to evaluate your infant's auditory nerve, cochlear, and hearing pathways to the brain. BERA Test examines the time taken for an electrical signal to reach from the inner ear to the brainstem.
