Can you hear a sonic boom from the ground?
Yes, a sonic boom produced at 60,000′ can be heard on the ground. These measurements are from aircraft with different altitude.
How high can a sonic boom be heard?
The boom was produced by an F-4 flying just above the speed of sound at an altitude of 100 feet (30 m). In recent tests, the maximum boom measured during more realistic flight conditions was 1,010 Pa (21 psf).
How long does it take to hear a sonic boom?
This shock wave will follow the plane as long as it flies at supersonic speeds. The effect doesn’t just occur once as the plane reaches and passes the speed of sound. Observers on the ground, along the plane’s entire flight path, will hear the sonic boom one to 60 seconds after the aircraft passes overhead.
When does a sonic boom reach the ground?
Depending on the aircraft’s altitude, sonic booms reach the ground two to 60 seconds after flyover. However, not all booms are heard at ground level. The speed of sound at any altitude is a function of air temperature.
What causes sonic boom when an aircraft exceeds the speed of sound?
When the aircraft exceeds the speed of sound, these pressure waves combine and form shock waves which travel forward from the generation or “release” point. As an aircraft flies at supersonic speeds it is continually generating shock waves, dropping sonic boom along its flight path, similar to someone dropping objects from a moving vehicle.
How big is the strongest sonic boom ever recorded?
The strongest sonic boom ever recorded was 144 pounds per square foot and it did not cause injury to the researchers who were exposed to it. The boom was produced by a F-4 flying just above the speed of sound at an altitude of 100 feet.
How much sonic boom can you get per square foot?
And, typically, community exposure to sonic boom is below two pounds per square foot. Ground motion resulting from sonic boom is rare and is well below structural damage thresholds accepted by the U.S. Bureau of Mines and other agencies. Characteristics
