Speech Intelligibility as a Function of Ambient Pressure and HeO2 Atmosphere.

Abstract

Speech intelligibility was obtained on Navy divers at sea level (in air) and at 200, 450 and 600 feet in helium-oxygen breathing mixtures. A total of 46 diver/talkers were studied (28 at 0 and 200 feet, 22 at 0 and 450 feet, and nine at 0 and 600 feet). Listeners were 15 University of Florida students trained for tasks of this nature. The combined effects of He02 mixtures and high ambient pressures were extremely detrimental to speech intelligibility which was reduced by approximately 50% for each increase of 200 feet of depth.
