Abstract:

The MA-1A Air Conditioner is an engine-driven air conditioner designed to provide conditioned air to the aircrafts interior during ground servicing. This report provides measured data defining the bioacoustic environments produced by this unit operating outdoors on a concrete apron at normal ratedloaded conditions. Near-field data are reported for 36 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 Volum 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
