COMMUNITY NOISE CAUSED BY SMALL AIRCRAFT AND NOISE OF SMALL AIRCRAFT IN TAKEOFF CONFIGURATION

A case study of the clash of an expanding community and the airport is described on the example of a typical growing small community airport. From a compliant study a good criterion for a model quiet light aircraft was derived - it should not produce more than 63 dBA SPL at ground level when flying over at an altitude of 500 ft. Three quieting procedures were studied: modified operational procedures, engine exhaust silencing, and propeller redesign plus engine gearing. It is found that propeller noise, the dominant portion of the total noise, can be reduced by using lower tip speeds, typically achieved by a slower turning, larger diameter propeller.
