Features of the Speech Signal During the Cumulative Action of Coriolis Accelerations,
Abstract
This report describes an investigation into possible variations of the acoustic characteristics of a speech signal caused by the cumulative action of Coriolis accelerations and subsequent nausea in the subject. Results indicate that for short exposures of up to 1 minute of Coriolis accelerations the speech intensity is raised by 1 to 2dB and the basic tone frequency increases significantly. However during the onset of nausea the speech intensity falls below the initial value by 1 to 2dB and the basic tone frequency is reduced. (Author)
