[Brain stem potentials evoked by "click" (author's transl)].
The authors describe the results of click at a recurrence frequency of 10 C/S in evoked responses of the brain stem, firstly in twenty normal individuals, with headphones or in a free area, making it possible to define a range of physiological responses to the different intensities, then in seventeen pathological individuals consisting of six cases of conduction deafness and eleven of perceptive deafness. On the basis of this study, they attempt to demonstrate the value of this type of examination not only in the determination of objective auditory threshold, but also in that of the type of deafness: conductive or perceptive. The method even makes it possible to approximately define the general appearance of the frequency distribution at the threshold according to the slope of the different latencies of P5. In the opinion of the authors, the chief advantages are the decrease in the time required for the test and the possibility of its use in the study of prosthetic gain.
