Abstract

There is a close correlation between the sound pressure of tone burst required to affect a primary auditory neuron at its characteristic frequency and that which will produce a detectable N₁ response at the same frequency. Units with thresholds from 80–0 db SPL (recorded from damaged and undamaged cochleas) were 0–20 dB, respectively, more sensitive than the action potential response.
