Abstract:This study examines the behavior of secondary sonic booms on United States (U.S.) coastlines to have a more complete understanding of the impact of supersonic travel on communities. Secondary sonic booms occur when the atmospheric conditions are such that the atmospheric refraction causes the sound that would ordinarily not reach the ground to bend toward the ground. NASA's PCBoom software is a preferred simulation tool to predict the location and pressure signatures of sonic booms. It was expanded to include secondary boom propagation but has not yet been rigorously used for secondary sonic booms in a variety of conditions. This study looks at how secondary sonic booms change throughout the year and how they behave at different U.S. coastline locations.
