Sound molecules can stack up in front of airplanes traveling at very high speeds. this can cause what?

Answer 1

Loud noises could cause damage to people's ears.

Answer 2

Loud noises could cause damage to people's ears.

Answer 3

Loud noises could cause damage to people's ears.

Answer 4

sonic boom

Answer 5

There is no such thing as a "sound molecule" so the answer to the question is no. The sonic boom associated with supersonic flight is associated with pressure waves built up in front of the aircraft (like the bow wavers from a boat) that radiate outward at supersonic speeds. These create a sound.

Answer 7

Sound is not molecules, it is pressure waves in a gas, liquid, or solid (which are composed of molecules).

What happens to the waves depends on how high the speed of the aircraft is:

• If the aircraft moves at a speed less than the speed of sound the pressure waves travel freely away from it.
• If the aircraft moves at the speed of sound or higher than the pressure waves are unable to leave the leading edges of the aircraft and they stack up forming standing waves (relative to the aircraft) of high pressure. Just behind this pressure wave the pressure drops equally suddenly and in humid air water vapor can condense into a cone shaped "cloud" that follows the aircraft. As the aircraft passes observers they hear this pressure wave (which is moving relative to them) as what is called a "sonic boom" (it is not heard on the aircraft as it is stationary there). On improperly designed aircraft these standing pressure waves can push on control surfaces on the wings and tail, making the aircraft hard to control and maybe even causing a crash (in the early days of developing supersonic aircraft test pilots were sometimes killed in such crashes before these effects were understood).

Answer 8

There's no such thing as "sound molecules".
