Abstract: The purpose of the study was to assess whether, and to what extent, hyperviscosity of whole blood should be considered as a potential etiological factor for hearing impairment. Thirty guinea pigs were maintained in decreased atmospheric pressure for different periods of time, between one and eight weeks. The stay in this hypobaric condition induced different degrees of rise in hematocrit. The damage to the cochlea was evaluated by measurements of the compound action potentials.
