Read Sound at the Field for more information. Propeller tip velocity chart will help you meet sound level rules. Information on other factors affecting noise generation and propagation are included. Electric Ducted Fan (EDF) systems must also comply with club noise level limits. Some gliders may also require noise reduction depending on design of the system.
