Abstract:

The AM32C-4 Air Conditioner is an electric motor driven unit providing heating or cooling to aircraft cockpits or electronic equipment during ground maintenance. This report provides measured data defining the bioacoustic environments produced by this unit operating inside a large aircraft hangar at normal rated conditions. Near-field data are reported for 37 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. Refer to Volume 1 of this handbook, USAF Bioenvironmental Noise Data Handbook, Vol 1 Organization, Content and Application, AMRL-TR-75-501 1975, for discussion of the objective and design of the handbook, the types of data presented, measurement procedures, instrumentation, data processing, definitions of quantities, symbols, equations, applications, limitations, etc. Author
