[EEG-audiometry at hyperbaric environments (author's transl)].

Within the framework of the complex studies on divers (subjective audiometry, EEG, ECG ect.) before, during and after a simulated diving in a barometric chamber up to 75 m (8.5 atm), an EEG-audiometry was applied on 5 persons. It is established that the amplitude of all components of auditory evoked responses during the stay at the "Bottom" is reduced, and in the period of de-saturization (especially at later decompression stages) grows and exceeds the initial one (especially N1P2- and N2P2-components) and others. In conclusion it is admitted that the changes in the values of the auditory function, tested by means of EEG-audiometry methods are a promising index of the state of the auditory analyzer.
