The myth that sonic booms easily cause building damage likely dates back to an infamous series of tests conducted in 1964 under FAA supervision wherein supersonic fighter jets flew over Oklahoma City eight times a day for six months. In the end 73% of surveyed residents said they could tolerate the booms indefinitely.
High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage. The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and might kills you. Can sonic booms damage your ears? The answer is, no, a sonic boom will not hurt your eardrums.
How much damage can a sonic boom cause?
There is a probability that some damage — shattered glass, for example, will result from a sonic boom. Buildings in good repair should suffer no damage by pressures of less than 16 pounds 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.
Can a sonic boom kill you at close range?
I don’t believe a sonic boom contains enough energy to kill a person even at close range; what’s going to kill you is more likely the energy from the source of the sonic boom rather than the sonic boom itself such as lightning (of which thunder is the sonic boom) or explosions. 8 clever moves when you have $1,000 in the bank.
A sonic boom can severely damage your hearing if you are close enough to the source. Is making a sonic boom illegal? Making sonic booms was banned in 1973. It is prohibited for anyone to operate an aircraft that is capable of producing sonic booms over densely populated areas.
Thoughts of using the sonic boom as a weapon seem to have been given up ; considerable civilian research is being done now on “Low Boom” supersonic flight.
Why is a sonic boom so loud?
They have the ability to move faster than the speed of sound. The constant expansion and contraction of air can cause a shock wave that sounds like a loud clap to human ears. This is why a sonic boom can be so loud.
The change in pressure caused by sonic boom is only a few pounds per square foot — about the same pressure change we experience on an elevator as it descends two or three floors — in a much shorter time period. It is the magnitude of this peak overpressure that describes a sonic boom.
You can learn a lot about sonic booms by looking at the wakes boats leave in the water. If you toss a pebble in a pond, little waves will form in concentric circles and propagate away from the point of impact.
While we were writing we ran into the question “What is the maximum amount of pressure a sonic boom can cause?”.
Well, (Sonic booms created by supersonic aircraft flying at very low altitude that have generated over-pressure of between 20 and 144 psf have been experienced by observers without causing injury .) Greater than 2160 psf: damage to human lungs.
If the plane breaks the sound barrier and flies faster than the speed of sound, it produces a sonic boom when it flies past. The boom is the ” wake” of the plane’s sound waves .
How dangerous is a supersonic explosion?
The shock waves produced by a supersonic aircraft have enough energy to shatter glass and even damage buildings. Some studies claim to show that sonic booms from U. S. Navy testing in Vieques, Puerto Rico, increased the incidence of vibroacoustic disease, a thickening of heart tissue.
What would happen if an F-4 made a sonic boom?
The boom was produced by a F-4 flying just above the speed of sound at an altitude of 100 feet. In recent tests, the maximum boom measured during more realistic flight conditions was 21 pounds per square foot. There is a probability that some damage — shattered glass , for example, will result from a sonic boom.
