“Anytime you have a sharp sound exceeding 140 decibels, there is a non-negligible risk of hearing loss,” he said. The sonic boom from the October Starship launch measured up to 146 decibels in ...

The result, he says, is a shaped sonic boom that is 20 to 25 decibels lower than the Concorde. "Because you've taken out the higher frequencies and lowered the sound pressure in general somewhat ...

Muting the sonic boom has been a massive engineering challenge ... The resulting blast could reach 110 decibels, similar to a loud thunderclap nearby. Engineers thus created a design that seeks ...
