What's That About? Sound

Sounds

Sounds are made when objects vibrate. The vibration makes the air around the object vibrate and the air vibrations enter your ear. You hear them as sounds.

You cannot always see the vibrations, but if something is making a sound, some part of it is always vibrating.

 

Detection of sounds

Sound waves can travel through solids (such as metal, stone and wood), liquids (such as water) and gases (such as air).

Sounds are made when objects vibrate. The vibration makes the air around the object vibrate and the air vibrations enter your ear. You hear them as sounds.
