Can humans hear sonic booms?

All we see is the pressure wave moving down the aeroplane – it gives an indication on the instruments. And that's what we see around Mach 1. But we don't hear the sonic boom or anything like that. That's rather like the wake of a ship – it's behind us.

Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.

Most sonic booms aren't felt on land (most supersonic training flights are out over the ocean). Atmospheric events are difficult to detect with seismographs because they usually transfer very little seismic energy into the ground.

If you're WONDERing about how pilots handle sonic booms, they actually don't hear them. They can see the pressure waves around the plane, but people on board the airplane can't hear the sonic boom. Like the wake of a ship, the boom carpet unrolls behind the airplane.

In 1973, the Federal Aviation Administration banned supersonic commercial flights over land because of sonic booms — a prohibition that remains in effect today.

Spike Aerospace, founded in 2013 Max Kachoria of NASA, built an 18-passenger supersonic jet with low-sonic boom, fuel efficiency, speeds up to 1,100 mph, and flight times slashed in half. Their current model is the S-512 which can get passengers to cities in a moment's notice: NYC to London: 3 hours.

Currently, U.S. law prohibits flight in excess of Mach 1 over land unless specifically authorized by the FAA for purposes stated in the regulations. The two supersonic rulemaking activities would not rescind the prohibition of flight in excess of Mach 1 over land.
