Experimental results obtained by a combination of fluid mechanics and radiated noise measurements associated with subsonic jets over a range of simulated flight speeds between 25 m/s and 110 m/s indicate that noise reduction in flight is predominantly a result of the reduced noise producing volume. These results do not support the generally accepted notion that noise reduction from jets in motion results primarily from the reduced strength of the noise producing eddies. (DePo)
