The development of certification procedures relies heavily on the results of aircraft noise research involving flight tests, and full scale and model scale wind tunnel tests. The most recent versions of the relevant noise certification procedures for regional aircraft, specifically for so called heavy and light propeller driven airplanes, are discussed. Relevant research in the area of propeller noise generation and radiation is described and an outlook on advanced technology propulsion systems (specifically the propfan) and the problems likely to be encountered in establishing corresponding noise certification procedures and noise limits is given.
