How does sound work?

We hear sounds when the vibrating waves enter our ears

These vibrations are called waves

Mechanical vibrations that are able to travel through all forms of matter: gases, liquids, solids, and plasmas.

The vibrating thing causes the space (air) around it to vibrate

The speed of sound is influenced by what it travels through and the factors affecting what is travels through. For example, altitude, humidity and temperature might affect sound waves traveling through the air.

Sound is produced when something vibrates.
