Therefore, for a boom to reach the ground, the aircraft's speed relative to the ground must be greater than the speed of sound at the ground. For example, the speed of sound at 30,000 feet (9,100 m) is about 670 miles per hour (1,080 km/h), but an aircraft must travel at least 750 miles per hour (1,210 km/h) (Mach 1.12) for a boom to be heard ...
The crack a whip makes is produced when a section of the whip moves faster than the speed of sound creating a small sonic boom. The creation of the sonic boom was confirmed in 1958 [1] by analyzing the high-speed shadow photography taken in 1927. [2] [3]
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.

A boom occurs when an object travels faster than the speed of sound, releasing a burst of energy that sounds similar to an explosion and can shake and rattle objects in its path.
On 15 October 1997, 50 years and 1 day after the sound barrier was broken in aerial flight by Chuck Yeager, Green reached 763.035 miles per hour (1,227.986 km/h), the first supersonic record (Mach 1.016). His call sign was "Dead Dog". As the vehicle exceeded the speed of sound it created a sonic boom.
If the wave is a sound wave and the sound source is moving faster than the speed of sound, the resulting shock wave creates a sonic boom. Lord Rayleigh predicted the following effect in his classic book on sound: if the observer were moving from the (stationary) source at twice the speed of sound, a musical piece previously emitted by that ...
