The auditory brainstem response (ABR) is a true neurological potential that that occurs within the brainstem in response to an auditory stimulus.
The ABR typically occurs 15 milliseconds after presentation of the stimulus.
ABR testing uses averaging to accumulate the tiny ABR response hidden in the noise, displaying the response amplitude from the brainstem over time.
Electrocochleography (ECochG) is a measure of the electrical potentials of the cochlea.
Typically, the measurement is characterized by the stimulus onset (baseline), the response of the cochlea to the stimulus (summating potential), and the response to the synchronous firing of nerve fibers (action potential).
"Our clinical study on infants and toddlers found that the Eclipse ASSR was faster and produced lower thresholds than our best ABR protocol."

"The Eclipse has the largest number of clinically-relevant features of any AEP device today. The platform is an excellent blend of parameter flexibility and user-friendliness."

"In 2005 we started to use the Interacoustics Eclipse EP-25 which as a turning point for us. A very user-friendly interface, fast and reliable equipment."
