Breaking The Sound Barrier: Can Pilots Hear Sonic Booms?

The video explains the phenomenon of a Sonic boom, which occurs when an object travels faster than the speed of sound. It describes how sound waves form a Mach cone, leading to the loud boom heard on the ground. Inside the plane, passengers and crew do not hear the boom due to their position at the head of the Mach cone. The video also covers how sound travels through air and the internal sound dynamics within a supersonic aircraft, ensuring that sound levels remain unchanged for those on board.

What happens to sound waves when a plane exceeds the speed of sound?

• They disappear completely.

• They bunch up in front of the plane.

• They spread out evenly in all directions.

• They slow down significantly.

Why don't passengers inside a supersonic jet hear the sonic boom?

• They are moving faster than the sound waves.

• The plane is soundproof.

• The sound waves are absorbed by the plane's body.

• The sonic boom is too quiet to be heard.

How does the speed of air affect the perceived speed of sound?

• It has no effect on the speed of sound.

• It reverses the direction of sound.

• It decreases the speed of sound.

• It increases the speed of sound.

What ensures that sound levels inside a supersonic plane remain unchanged?

• The plane's speed matches the speed of sound.

• The internal air travels at the same speed as the plane.

• The plane's engines are silent.

• The plane's body absorbs all sound.

How can pilots still hear their own voices inside a supersonic aircraft?

• The plane's body blocks external sounds.

• The plane's speed amplifies internal sounds.

• Sound is transmitted through the air inside the plane.

• The cockpit is isolated from external noise.
