HYPOXIA AND HEARING – WHAT DO WE REALLY KNOW?
Journal Title: Medicina Sportiva - Year 2012, Vol 16, Issue 2
Abstract
Due to the fact, that the hearing process is an energy-depended and consumptive process, some changes happen, when going to high altitude where the oxygen partial pressure decreases. The oxygen is provided to the inner ear by diffusion over a relatively large distance. Because the amount of material decreases with the square of the distance high noise levels at altitude or in isobaric hypoxia must be assumed as a stress situation for the inner ear. There are only a few data about a temporary or permanent threshold shift in hypoxia or an increased sensitivity of the ear for occupational noise disease in such conditions. The hearing loss due to hypoxia at altitude or in isobaric hypoxia is a central-nervous hypoxic dysfunction and not rarely a sign of a beginning HACE. We review the actual knowledge about this topic.
