sonic boom

As the cone spreads across the landscape along the flight path, they create a continuous sonic boom along the full width of the cone's base.

Such "sonic boom clouds" can occur when aircraft fly fast enough to cool the air around them, causing moisture in the air to condense.

This time we'll look at how the size and altitude of a plane influence the intensity and duration of the sonic boom.

The much talked about sonic boom was considered socially unacceptable and meant Concorde was restricted to flying supersonic over the ocean.

It is the rate of change, the sudden onset of the pressure change, that makes the sonic boom audible.

Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.

The ratio of aircraft length to maximum cross sectional area also influences the intensity of the sonic boom.

The sharp release of pressure, after the buildup by the shock wave, is heard as the sonic boom.

Of all the factors influencing sonic booms, increasing altitude is the most effective method of reducing sonic boom intensity.

Shatalov surmises that the shock wave from another plane's sonic boom was to blame.

Breaking the sound barrier generates a sonic boom, so supersonic travel is heavily restricted over land.

The fireball briefly turned night to green-tinged day and unleashed a sonic boom heard for hundreds of miles around.

Will I cause a dream sonic boom if I go faster?

But Aerion reckons that a far better approach is to abandon efforts to reduce the sonic boom and fly supersonic only over water.

This is, of course, the reason why a sonic boom hits us with all its fury from a supersonic aircraft but not from a subsonic one.

Sonic boom has become the most critical technology limiting civil aircraft's supersonic flight over land.

The sonic boom, however, will not be uniform.

Faster than around Mach . 85 -- or 85% of the speed of sound -- friction, turbulence and sonic boom cause big headaches.

Wizz Products supplies household cleaning and laundry products under the Wizz, Oxi Ultra Plus, Sonic Boom and Pink Stuff brands.

Most of the noise a gunshot makes is expanding gases, and there's the tiny sonic boom a bullet makes because it travels so fast.

In this case, the 33 megajoules launched the shot 5, 500 feet per second, exceeding the speed of sound and releasing a sonic boom.

An aircraft, for example, flying supersonic at 50, 000 feet can produce a sonic boom cone about 50 miles wide.
