Abstract
Under the highly dynamic and demanding working conditions experienced by the Canadian Forces, exposure to noise and vibration in vehicles is often dismissed as merely a source of annoyance and discomfort. Evidence that prolonged and repeated exposure to whole−body vibration causes adverse health effects has been well documented in literature, but few studies have investigated the effect of vibration on human cognition and communication. For military personnel, sharp situational awareness and clear communication between crewmembers are essential for effective performance and, ultimately, survival. Previous studies on the effects of exposure to whole−body vibration and noise on human cognition and communication are reviewed. Future directions for research are proposed in the interest of determining and quantifying the effects of different magnitudes and frequencies of noise and vibration on cognition, speech intelligibility and hearing in military vehicle operators.
