[The usefulness of provoked acoustic otoemissions in the study of olivo-cochlear reflex].
The paper reports the experimental task done by the AA, in order to probe objectively the being of a feed-back circuit of cochlear interconnexion. This loop is basically represented by the medial efferent olivo-cochlear system. With that purpose they have analyzed the variations produced in the provoked acoustic otoemissions by clicks registered in one ear when the contralateral ear is stimulated with a white noise of 80 dB HL. The results shows that after stimulation of the contralateral cochlea with a white noise a decrease of the global amplitude of the PAOE is observed and also a decrease of the several amplitudes composing the frequency spectrum, but retaining the same morphological pattern.
