Sonic booms from supersonic planes have harmed people’s hearing, shattered windows and caused other physical damage to homes and buildings.
“The noise levels induced by these lower-level booms are still expected to be significant,” says study coauthor Didier Dragna of the École Centre de Lyon in France.
Dragna and colleagues simulated booms from supersonic planes passing over buildings. For a building standing out in the open, boom-induced noise lasted about a tenth of a second. Sound reflecting from the building boosts noise levels slightly for the side facing an approaching plane and reduces it on the side facing away.
For packed cityscapes, however, noise reflected from buildings following a sonic boom fills in the regions between buildings and. Their simulations showed that even after the initial boom has passed the noise persists for several seconds, creating what Dragna describes as a thunderous, window- and door-rattling rumble.
Civilian aircraft in the United States are generally prohibited from traveling over land at supersonic speeds. But NASA will begin test flights of its “quiet” over cities in 2024. “It is important to predict what will be the noise levels and the annoyance due to these supersonic planes,” Dragna says.
