Sound (compression) waves.
Mechanical waves require a medium.
Waves that require a medium through which to travel are called mechanical waves. They require a medium (gas, solid, and liquid).
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
A mechanical wave requires a medium to transfer the energy it carries, unlike EMR waves. There are several types of mechanical waves, most of them being found in an earthquake. Mechanical waves are all longitudinal waves.
Longitudinal waves require a medium to propogate . Example are sound waves
Electromagnetic waves.

A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .

Mechanical waves
The two waves which do not require a medium are electromagnetic waves, also known as light and gravitational waves. Gravity waves have not been detected yet but are predicted by general relativity so are expected to exist.
