The present work is part of a program, the objective of which is to find practicable ways of reducing the external noise level of light airplanes in order to make them less objectionable to persons on the ground. This report covers noise measurements on standard light airplanes and on similar airplanes equipped with engine mufflers, propeller reduction gears, and propellers with various numbers of blades and blade shapes.
