CONCEPTUAL STUDY OF SONIC ENERGY CONTROL TECHNIQUES.
Abstract
In current aerospace vehicles failure or mal function of instrumentation or componnents has been attributed in some cases to the intense noise environment characteristic of the operation of such vehicles. With the advent of more power ful vehicles in the future the problem is expect ed to become more severe. An analytic study has been made of several methods of noise control applicable to the special situation of the aero space vehicle. The methods considered include (1) the use of the concepts of mechanical impedance and rheological models for noise and vibration control (2) the use of thin shelled structures as noise shields and (3) the adapta tion of conventional methods of noise control to the special circumstances of the operation of aerospace vehicles. The analysis presents basic principles involved in the various methods, discusses procedures by which the protection afforded may be predicted, discusses the param eters which determine effectiveness, and presents recommendations for additional research.
