USAF Bioenvironmental Noise Data Handbook. Volume 149. C-9A In-Flight Crew/Passenger Noise.

Abstract

The C-9A is a McDonnell Douglas DC-9 series 30 commercial transport modified to perform aeromedical evacuation missions. This report provides measured data defining the bioacoustic environments at flight crew/passenger locations inside this aircraft during normal flight operations. Data are reported for 56 locations in a wide variety of physical and psychoacoustic measures: overall and band sound pressure levels, C-weighted and A-weighted sound levels, preferred speech interference level, perceived noise level, and limiting times for total daily exposure of personnel with and without standard Air Force ear protectors.
