Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

Can sound travel without air?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

How do we hear sound?

We hear when sound waves travel through the air to our eardrum, across our middle ear, into our inner ear, and finally to the auditory centres of our brain. Our ears are always on and are continuously carrying sounds along this hearing pathway.

What is sound made of?

Sounds are created when something vibrates (shakes back and forth), sending waves of vibrations into the ears of the listener. When a bell is struck, the metal vibrates. The vibrations travel through the air as sound waves.
