CHANGES IN GROUND NOISE LEVELS OF GENERAL AVIATION AIRCRAFT DERIVED FROM CHANGES IN COCKPIT NOISE LEVELS

It is suggested that measurements of changes in cockpit (cabin) noise levels can be used to estimate the noise levels associated with various power settings of general aviation aircraft in their operations about an airport. Data on cabin noise levels during takeoff and landing would be used to adjust data obtained under a standard 1000-ft high power condition so that it would apply to climb, cruise, and other conditions. Changes in cabin sound levels as a function of flight condition are presented for a single-engine type and a twin-engine type aircraft. Ground measurements of noise changes were obtained for one of the aircraft types in order to test the validity of the procedure.
