Cortical Evoked Response Audiometry (CERA) Testing

A CERA or Cortical Evoked Response Audiometry is an objective hearing test, that records the signals from the auditory cortex (part of the brain that recognises sound) that have been generated in response to sounds introduced to the ears. 

The test gives information about the level of sound needed to produce a signal and confirms the status of the auditory cortex.This is valuable information that we can not obtain from a normal hearing test. 

The CERA appointment takes approximately two hours to complete and you’ll be asked to bring a book so you or your child can be as relaxed as possible during the test.  It involves placing electrodes behind the ears and on your head and these are then connected to the computer. A series of tones at various loudness levels are then produced to help us analyse the responses. 

We perform CERA tests for ENT Consultants, Solicitors and Medico-Legal agencies.
