[Recording of evoked otoacoustic emissions in adult normal hearing population. Percentile of normalcy].

Evoked otoacustic emissions recording hold some promise as a fast objective and non-invasive audiological procedure to study the cochlea at the outer hair cell level. This study has been made in 100 voluntary normal hearing adults. We evaluate the auditory system by means of evoked otoacustic emissions with a non-linear click. This report resumes methods and results in these normal grown-up ears.
