Abstract

This presentation reviews recent studies that have been carried out by Wyle Laboratories on noise from military aircraft operations. Four different areas of research will be described—modeling, measurements, psychoacoustics, and noise control. The discussion of subsonic aircraft noise models includes NOISEMAP, ROUTEMAP, MR—NMAP, and the Rotorcraft Noise Model, while that of supersonic noise models includes CORBOOM, BOOMAP3, and PCBOOM. The discussion of aircraft noise measurements includes sonic boom monitoring, military training route measurements, NOISENET, potential damage to unconventional structures by sonic boom, and rotorcraft noise measurements. The psychoacoustic discussion includes the development of the onset rate correction for high-speed, low-flying military jet overflights and community response to sonic booms. The discussion of aircraft noise control will describe the use of active noise control to reduce noise from hush houses and static jet engine runups.
