Including Electrocochleography (ECochG), Auditory Brainstem Responses (ABR), middle and late latency response.

An ECochG is looking for an indication of the presence of endolymphatic hydrops. The test records the response of the cochlea and the firing along the auditory nerve.

An ABR is most commonly used to test for retrocochlear function as well as test hearing thresholds for clients who cannot carry out a behavioural test as well as for workers compensation clients.
