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

Objectives: A number of stimulus presentation features of the tone burst-evoked N1-P2 cortical response were investigated to identify any advantage over simple stimulation when the test is used for hearing threshold estimation. The speed of establishing objective thresholds at 1, 3, and 8 kHz in both ears was also measured in what was designed to be an efficient test protocol, …

In response to sound stimulation, neural electrical potentials are produced by various parts of the auditory system from cochlea to cortex. Evoked response audiometry (ERA) is the technique designed to measure these signals. No conscious response is required from the patient, thus these tests can be considered as more objective measures of the auditory system …

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).

Auditory cortical response: Records the impulses generated by brain in response to tone stimuli. It is recorded using cortical response audiometry (CERA). CERA is very useful for threshold estimation of hearing, where as BERA is highly useful for objective threshold estimation of hearing as well as differential diagnostic purposes.

Conclusion: Speech thresholds measured using Cantonese Hearing in Noise Test (CHINT) and cortical evoked response audiometry (CERA) thresholds were highly correlated with pure-tone behavioral results. Both tests are considered to provide good estimates of hearing thresholds and can be employed to confirm the degree of hearing loss in Cantonese-speaking communities.
