Workshop report for the AIAA 5th Aeroacoustics Conference

Summaries of current understandings, technological tools and remaining controversies in the field of aeroacoustics are presented, with attention also given to developments in means of noise suppression to comply with proposed and projected regulations. Topics include jet noise mechanisms and their suppression; turbomachinery noise, including noise sources, noise prediction by the modal approach and experimental methods; duct acoustics, with discussion of sound attenuation and propagation, the application of finite element methods, and the radiation of sound from inlets; helicopter rotor, airplane propeller and V/STOL noise; aircraft interior noise; and general acoustics, atmospheric propagation and the sonic boom.
