“…For the four temporal instances evaluated, the maximum range in undertrack level was 11.7 PLdB during a six-month period as well as a 12 h period. These results are in agreement with other studies performed by Salamone [31] and Heimann [30]. Furthermore, only the undertrack (i.e., sound emitted directly below the aircraft) perceived level was evaluated, but it is possible that the offtrack signature leads to even higher loudness magnitudes [5].…”

“…by considering only one instance in time [32], averaging atmospheric profiles across years [31], sampling a sparse selection of days throughout the years [3,30], evaluating only locations on the flight path [32,34,35], or selecting locations that are representative of different climates [31,33]. However, this study proposes a broader analysis of atmospheric states, allowing analysis of other factors previously not studied and validating previous results from the available literature.…”

U.S. national research priorities include reducing the disruption caused by sonic booms, which hindered the economic viability of supersonic aircraft in decades past. However, shock waves are unavoidable during supersonic flight; and exposure of people, animals, and structures to these shock waves on the ground cannot be eliminated entirely. It is herein shown that changing atmospheric conditions, gusts, and heights above ground can result in any supersonic aircraft that is acceptably quiet at specific atmospheric conditions becoming uncomfortably loud in other flight conditions. These performance variations are noticeable for periods ranging from 12 h to one year across the continental United States of America. Therefore, strategies to actively mitigate sonic booms may become necessary as researchers work toward resumption of overland commercial supersonic flight.
