Investigation of Ground Crew Noise Exposure for the Royal Canadian Air Force CH-149 Cormorant Helicopter

摘要

Royal Canadian Air Force (RCAF) CH-149 Search and Rescue helicopters operate in extreme and strenuous environments often with doors open configurations. Due to the demanding nature of search and rescue activities, civilians, aircrew and ground crew may be exposed to noise exposure events without properly fitted hearing protection. This paper outlines the National Research Council's (NRC) ground external noise measurement of the CH-149 Cormorant at Comox Canadian Forces Base.
