WebIn the case of the self-noise of ships, just as the radiated noise of ships, machinery noise, propeller noise, and hydrodynamic noise are the three major classes of noise sources. … WebSuccessively we evaluate the noise generated by simple, still significant, geometries, and finally we consider noise propagation from a ship propeller in uniform flow. For the latter we observe the tonal signal given by the blade rotational frequency together with a high amplitude broadband noise given by the wake. dio should have won
