Psychoacoustic and Electrophysiologic Studies of Hearing Under Hyperbaric Pressure.
Abstract
Work performed includes: calibration of laboratory standard Type-L condenser microphones to a simulated depth of 990 feet (31 ATA); Calibration of standard audiometric earphones to a simulated depth of 990 feet (31 ATA); and, measurement of human auditory thresholds during deep, saturation dives in helium-air. Human threshold data were collected at numerous depths during compression and decompression for air conduction and bone conduction to a simulated depth of 990 feet (31 ATA). Electrophysiological measurements were recorded from experimental animals under similar conditions. (Modified author abstract)
