[Electrophysiologic characteristics of rapid auditory adaptation]

In 32 rabbits, dependence of character of fast auditory adaptation on frequency of the sound stimulation was shown. Specific features of the adaption in conditions of switching off of the inner ear receptors with streptomycine were revealed. The fast adaptation was concluded to have a peripheral mechanism. Methods of the adaptation studying with the acid of action potentials of the 8th nerve and microphone potentials of the cochlear were compared under conditions of sound overload, and differences in results of measuring the fast adaptation were explained from the standpoint of dependence upon intensity of sound simulation.
