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 4000Hz.

Objetivo

Actualmente el estudio de la audición mediante el registro y el procesamiento de los potenciales microfónicos cocleares está en fase de validación definitiva respecto a los resultados que se obtienen mediante otros procedimientos objetivos. El propósito de esta aportación es contribuir a esa validación.

Material y método

Se ha empleado equipo destinado exclusivamente al registro de los microfónicos cocleares realizando el estudio en adultos para poder comparar los resultados audiométricos subjetivos con los obtenidos mediante microfónicos cocleares.

Resultados

Presentamos una concordancia estadística entre la audiometría subjetiva y la audiometría microfonicococlear.

Conclusiones

Dada la equidad de resultados, el procedimiento resulta válido muy especialmente en el diagnóstico precoz, en el que se consigue un perfil idéntico al del audiograma subjetivo en las frecuencias audiométricas 250, 500, 1.000, 2.000 y 4.000Hz.
