Objective:
The recording and processing of cochlear microphone potentials in hearing studies is currently in the definitive validation phase against results obtained with other objective procedures. The purpose of this work is to contribute to its validation.
Material And Method:
The equipment used was exclusively designed for recording cochlear microphone potentials. The study has been carried out in adults to compare subjective audiometric results with those obtained from cochlear microphones.
Results:
We present a statistical concordance study between subjective audiometry and cochlear microphone audiometry.
Conclusions:
In view of the results obtained, this method is particularly valid for early diagnosis. We obtained an identical profile to the subjective audiogram at audiometric frequencies of 250, 500, 1000, 2000, and 4000 Hz.
