Abstract

The cochlear initiation of the frequency-following response (FFR) to 500-Hz tone bursts was assessed in 6 normal-hearing subjects by measuring FFR amplitude as a function of the low-frequency cutoff of high-pass masking noise (3 550, 1 800, 900, and 450 Hz). The major fall off of FFR amplitude occurred when the masking noise began to mask the apical portion of the cochlea. This effect was especially apparent at low intensities. The results are interpreted as supporting the view that at low intensities, low-frequency tone bursts evoke the FFR primarily through the apical portion of the cochlea.Dans cette expéerimentation nous avons utilisé un bruit de masquage filtré passe-haut (la fréquence de coupure étant 3 550, 1 800, 900 ou 450 Hz) pour déterminer, en fonction de la hauteur de la fréquence de coupure, l'amplitude de la réeponse suivant la fréquence (FFR) à des «tone-bursts» de 500 Hz. La plus grande diminution de l'amplitude de la FFR débute lorsque le masquage commence à atteindre la portion apicale de la cochlée; cet effet est particulièrement net pour les intensités faibles. Ceci confirme notre opinion, à savoir que des tone-bursts de faible intensite évoquent des FFR essentiellement à partir de la portion apicale de la cochlée.
