AN effective method for silencing, to an agreeable amount, the noise produced by a jetengine exhaust system is described in this paper.The principle employed is based on the fact that high-frequency noises are more rapidly attenuated with increasing distance from the source than low-frequency noises. Basically, the performances of the developed silencers are to reduce the amount of noise of a jet exhaust by increasing the frequency range of the noise produced.Full-scale silencers have been developed for use as ground equipment. Scale models of airborne silencers have been studied and show promise for full-scale development, however, further studies are required to minimize disadvantages to airborne applications.
