Sonic boom and the "rise time" of the shock which makes the boom seem louder. On most aircraft designs the characteristic distance is about , meaning that below this altitude the sonic boom will be "softer". However, the drag at this altitude or below makes supersonic travel particularly inefficient, which poses a serious problem. The pressure from sonic booms caused by aircraft often are a few pounds per square foot. A vehicle flying at greater altitude will generate lower pressures on the ground, because the shock wave reduces in intensity as it spreads out away from the vehicle, but the sonic booms
Acoustic shock shock at work. BT has already paid £90,000 to one worker that suffered from tinnitus. In March 2018, a musician won a claim for damages against the British Royal Opera House for acoustic shock caused by excessive noise during orchestral rehearsals.
