Pure tone audiometry (hearing test)

A hearing test also known as pure tone audiometry measures the quietest sounds you can hear in sound-proof conditions. Its purpose is to verify the degree and type of any hearing loss.

During the hearing test you will be required to wear headphones or ear inserts and press a small button in response to a variety of tones at various levels of frequency and intensity. A full detailed report of a client’s hearing can be provided to explain the hearing test results. We can also discuss the appropriateness of hearing aids or further diagnostics investigations can also be recommended. Pure tone audiometry is adaptable to suit young children and learning disabled adults.

Cortical Evoked Response Audiometry (CERA)

A CERA or Cortical Evoked Response Audiometry is an objective hearing test, that records the signals from the audiometry 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.
