The trailing edge treatments as now found on some jet aircraft engines and my own hovercraft leading edge splitter/diverter experiments back in 2008 were based on breaking up the sound nodes or peak frequencies which account for perceived loudness by distributing the sound energy across a wider spectrum and leveling it out some.
Sample:
Hovercraft - Experimental Skirt Project - Page 2 - Boat Design Forums
The leading edge in water is a different matter.
