Averaged-Evoked-Response Eeg Audiometry in North America

Abstract

Averaged evoked responses recorded from the vertex (V potentials) are a valid basis for “physiological audiometry” in infants and young children. Their responses are slower and more variable than in older children and adults. A response to tactile stimulation is a useful guide to the form of the auditory pattern if the auditory threshold is high. Good agreement among the eight or ten most active laboratories in North America has been reached on the desirable parameters of stimulation and recording. The values are summarized, and references are given to a significant recent publication from each laboratory.
