1、The new aircraft creates a sonic boom.
2、The sonic boom, however, will not be uniform.
3、Of all the factors influencing sonic booms, increasing altitude is the most effective method of reducing sonic boom intensity.
4、Now there are companies that will insure people for damage caused by a sonic boom.
5、Shatalov surmises that the shock wave from another plane's sonic boom was to blame.
6、a sonic boom follows an aircraft as a wake follows a ship.
7、Will I cause a dream sonic boom if I go faster?
8、Most people on the ground cannot distinguish between the two and they are usually heard as a single sonic boom.
9、The ratio of aircraft length to maximum cross sectional area also influences the intensity of the sonic boom.
10、An aircraft, for example, flying supersonic at 50,000 feet can produce a sonic boom cone about 50 miles wide.
11、It is the rate of change, the sudden onset of the pressure change, that makes the sonic boom audible.
12、The sharp release of pressure, after the buildup by the shock wave, is heard as the sonic boom.
13、If you encounter a sonic boom, is that evidence that an aircraft of some sort exceeded the speed of sound moments ago to become supersonic?
14、A sonic boom is the loud crash and shaking that happens when a jet plane goes faster than the speed of sound.
15、Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.
16、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.
17、The change in air pressure associated with a sonic boom is only a few pounds per square foot — about the same pressure change experienced riding an elevator down two or three floors.
18、A sonic boom is the loud crash and shaking that happens when a jet plane goes faster than the speed of sound. When this happens,a shock wave hits the earth and may break windows or cause ceilings to crack.
19、One example is provided by the sonic booms from airplanes.
20、Acoustics--Description and measurement of physical properties of sonic booms
21、The structure is intended to reduce the sound from annoying sonic booms.
22、From protection against enemies to social security to sonic booms, insurance has come a long way.
23、Lisa Block, spokeswoman for the Texas Department of Public Safety, said her agency had received calls from residents surprised by sonic booms about 11 a.m.
24、Thousands of people began to call in, swamping the 911 dispatchers with reports of sonic booms and metal falling out of the sky.
25、If you're not near an airport used by jets, you may not need to worry about sonic booms, but some people do suffer damage in this way.
26、The Concorde's limited range, and rules that forbade it from setting off sonic booms over land meant it mostly stuck to its transAtlantic back and forth.
27、The team used simulation tools to show it was possible to achieve over-land flight by dramatically lowering the level of sonic booms through the use of an "inverted-V" engine-under wing configuration.
28、Supersonic flights are allowed only over water-and are thus limited to connecting wealthy cities separated by an ocean-because sonic booms can damage things and annoy people on the ground.
