The Physiological Influence of Sound on the Cochlea Metabolism

Abstract

The additional degree of metabolically produced energy needed in physiological sound exposure (up to 100 dB) must be expected to be low in relation to the energy turnover at rest. a method of investigation in the living animal is presented, allowing the simultaneous registration of CM, oxygen tension, and some metabolites in the perilymphatic space. the sensitivity of the test was proved by dramatic alterations in the biochemical parameters effected by adrenalin or changes in the respiratory gas for the animal. Sound exposure up to 100 dB could not be detected in the investigated biochemical parameters.
