Abstract

The method for reducing noise radiation from propellers consists of providing at least one propeller blade with a damping layer of damping material or a damping structure. The damping layer is applied to the surface of the propeller blade and/or is integrated into the propeller blade structure. Also claimed are a propeller with such a noise damping layer, and an underwater or surface vessel with a noise-damped propeller.
