[Functional state of the human hearing analyzer exposed to +Gx acceleration].
The functional state of the acoustic analyzer of man was investigated during an exposure to +Gx acceleration of 4-14 g applied at an angle of 78 degrees to the long axis of the body. During an exposure to 8-10 g the hearing state began to deteriorate. This included an increase in the tonic thresholds of hearing sensitivity with respect to the aerial and bone conduction, and an increase in the differential thresholds of hearing with respect to the strength and pitch. With an increase of the acceleration value these changes grew, reaching maximum at 14 g. It is suggested that possible mechanisms of changes in the hearing sensitivity are associated with disorders in the systems of sound conveyance and perception.
