Electrical Threshold Estimation For Cochlear Implant Fitting - Interacoustics Eclipse Instructions For Use Manual

3.8.3 Electrical threshold estimation for cochlear implant fitting

Typically, eABR modes exist under the cochlear implant software.
The eABR test is a useful tool for estimating the current levels needed for each of the electrode bands, to
help assisting the cochlear device tuning.
In a typically eABR test each electrode band are not tested due to the lengthy procedure of testing the many
electrode bands. Instead interpolation is used across the recorded electrode bands. Below is an example of
the estimated eABR tuning for a Cochlear Freedom.

It is suggested to use the function waveform note, to add the CI current level used for each waveform.
Further information about eABR recordings can be obtained from Eclipse Additional Information Manual.
