Answer:

longitudinal waves

Explanation:

Sound waves are the mechanical and longitudinal waves. They travel in a medium as they always require a material medium for their propagation.

As the sound travels in air, it exerts pressure on air and the compression and rarefaction travels through the medium.

As the source emits sound waves, it creates pressure in air and the vibrations hit our ear drum due to which we can hear sound. If there is no medium between the source and ear drum, the sound waves do not travel and we do not hear any sound.
