Abstract
Attention is drawn to the fundamental difference in the mechanism wher eby air and marine propellers radiate noise, although it is referred t o as ''rotational noise'' in both cases. In modeling the noise held of a marine screw propeller, it is essential to allow for noise generate d by the hull. A simple mathematical model is proposed for noise gener ated by the propeller-hull system.
