Cortical Evoked Response Audiometry (CERA) refers to the technique of measuring ALRs for the purpose of assessing ones hearing abilities. The responses are typically measured using surface electrodes placed on the scalp of an individual. Why ALR? ALR/Cortical ERA is traditionally used to help determine the degree of hearing loss in adult populations. Compared to traditional …

Cortical Evoked Responses (CERA) Why? This is a test that uses sound stimulation responses to objectively assess your hearing thresholds. Basic audiometry tests, such as pure tone and speech audiometry, are subjective and rely on the subject to voluntarily indicate when a sound has been heard. Objective tests use a computer to measure the electrical activity in the auditory

Conclusions: This study suggests that cortical electric response audiometry has a performance that is as good as or better than the auditory brain stem response for threshold estimation in adults and that sophisticated stimulation techniques do not appear to be required. An efficient test protocol that automates many laborious tasks reduces the test time to less than half that …

The three tests in commonest use are as follows: 1. Electrocochleography. 2. Auditory nerve and brainstem-evoked potentials. 3. Cortical electrical response audiometry. 23.1 Electrocochleography Electrocochleography (ECochG) aims to measure the signal produced by the cochlea and cochlear nerve in response to acoustic stimulation. 23.2 Technique

Abstract: Cortical evoked response audiometry is adequate for approximating hearing threshold levels with frequency specificity when the psychoacoustic responses lack reliability and reproducibility (compensation claim). It is well-known that control of wakefulness is es sential for the reliability of slow vertex responses (SVR).
