Abstract
Fixed- and rotary-wing aircraft employed by the military contain subsystems, many of which generate noise. The author has attempted to survey the spectrum of secondary and auxiliary systems that produce acoustic noise that invades occupied areas of fixed- and rotary-wing aircraft. The variety of such systems are classified into exclusive categories and illustrations and acoustic descriptions are given for each group. A few systems described include: pneumatic and electrical power systems, environmental and pressurization systems, secondary mechanical power distribution units and systems, rain and ice control and removal systems, and others. In addition, contributions of the noise generated by such systems that elicit potentially undesirable auditory responses among crew-members and passengers are identified and discussed.
