Whistle while you ductwork: Predicting air leakage noise

Improperly sealed ductwork creates system inefficiencies and noise. When leaky ducts are exposed to occupied spaces, these radiated noises can be a significant nuisance as their characteristic is often hissy, tonal, and whistle-like. This presentation will offer an empirical method for predicting noise resulting from air leakage. The algorithm only requires knowledge of the duct velocity and size. Example scenarios and limitations of the method will be presented.
