The MD-4 Generator is a motor driven generator set designed to furnish alternating current for hangers, maintenance shops and industrial facilities where precision bench mockup and test equipment requiring precise power are operated and tested. This report provides measured data defining the bioacoustic environments produced by this unit operating inside a large aircraft hanger 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.
