Noise control technology applicable to supersonic transport (SST) category aircraft is evaluated in view of the restraints of the Noise Control Act of 1972, which restricts both the EPA and the FAA to noise regulations that meet considerations of 'safety, economic reasonableness, technological practicability, and appropriateness to type of aircraft.' The effect of such constraints on the design goal for second-generation SSTs is considered. The report contains five sections. Section 2 develops a basic perspective on the noise of subsonic and supersonic aircraft and the general relationships between their airframe and engine performance characteristics, noise certification standards, and noise impact. Section 3 summarizes the status of individual elements of noise control technology including engine, aerodynamics, and operational procedures. Section 4 reviews some of the integrated airframe-engine noise integration studies, and Section 5 attempts to summarize where noise and the SST stand with respect to technology. This report is based on information developed and made available prior to Fall 1978.
