The development of noise control is reviewed from the lobed nozzles and tubular jet noise suppressors used for the first family of jet powered aircraft to acoustic liners, current operational procedures and future technology for diminished aircraft noise. Community response can be related to noise exposure. The characteristics that combine to produce annoyance due to aircraft noise include: fear, susceptibility, distance adaptability, misfeasance-preventability, and physical noise exposure. To increase community acceptance, all of the following features must be considered: noise from the aircraft, aircraft operation, land use planning in the airport neighborhood, and along the incoming the outgoing flight tracks. The noise sources discussed include: jet, turbine, fan and compressor noise; shock wave from the blade tips causing 'buzz saw', and the noise caused by the high by-pass ratio engine. Operational procedures aimed at noise reduction, such as two segment approach procedure must take into account a wide margin of safety.
