Can a 747 break the sound barrier?

As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.

What frequency can kill you?

The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.

Can silence kill you?

It can’t be seen or heard; can take place indoors or outside; it’s not biological, environmental or radiation, but it can make you sick or kill. Your body reacts to sound, a train or plane passing by or your being too close to speakers can cause your body to shudder. …

Are sonic booms illegal?

In essence, that regulation prohibits anyone from operating a civil aircraft at a true flight Mach number greater than 1 over land in the United States and from a certain distance off shore where a boom could reach U.S. shores.

How fast do you have to go to break the sound barrier?

Can a sonic boom kill you?

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

Why do we no longer hear sonic booms?

Why don’t we ever hear sonic booms any more? Noise abatement regulations halted supersonic flight (by civil aircraft) over U.S. land. The Concorde could still take off and land here because it broke the sound barrier over the ocean, but it’s no longer in service.

Is there a sonic boom at Mach 2?

The wave speed for the sonic boom in air is the speed of sound. Whenever the plane is going faster than the speed of sound, it’s making a sonic boom that is always moving along with it. Nothing special happens at Mach 2. … This is exactly like the wave of a boat.

Do whips break the sound barrier?

“The cracking sound a bullwhip makes when properly wielded is, in fact, a small sonic boom. The end of the whip, known as the “cracker”, moves faster than the speed of sound, thus creating a sonic boom. The whip is probably the first human invention to break the sound barrier.

Can a sonic boom happen in space?

Its true there is no sound in empty interstellar space, but the Herschel space observatory has observed the cosmic equivalent of sonic booms. And it’s possible these shockwaves could generate sound within an interstellar cloud – if something were there to hear it. …

Does the pilot hear the sonic boom?

Is there a sonic boom when slowing down?

No. The “boom” is a shock wave that continues to travel with the speeding object as long as its speed exceeds that of sound; when it slows down below the speed of sound, the shock wave just goes away. … The shock wave is not an impulse occurring just the body goes faster than the speed of sound.
