Abstract:

The USAF OEHL was requested by HQ MACSGPE to evaluate interior noise levels on the C-9A Nightingale aircraft during aeromedical evacuation operations because of subjective opinion that the cabin has become more noisy in recent years. Measurements were made on 18 regular working flights of the 57th Aeromedical Evacuation Squadron AES, Scott AFB IL. Noise exposure data indicated hazardous noise levels in the rear of the cabin only. Crew-member noise exposures could be effectively limited by the use of hearing protection. Author
