metals
Steel, The greater the density, the faster sound travels through it.
when solids are packed tightly/closely together sound waves travel faster
simply air
Sound waves cannot travel through empty space because they require air particles to transfer them. UV is a light wavelength and can travel through space (just like light from the Sun reaches the planets).
It depends on the distance it has to travel.

Sound moves through water. It just moves more quickly than in air, so it's harder for humans to identify it.

The sound that comes from headphones are electronic pulses sent through the wire and reach your ear drum, which is vibrated and transformed into the sound that you hear.
a sound made by something moving quickly through the air and water
simply air
Vibrating 'air' particles, through a transfer of energy; creating a sound wave which then reaches your ears and vibrates your ear drum. (doesn't have to be air, sound also travels through water ect)
Air particles are much less dense than water particles, so the vibrations of sound can travel through air more quickly.
