A completely empty space is called a vacuum. A vacuum does not even have air. Sound cannot travel through a vacuum.
A totally empty space (containing neither air nor anything else) is called a vaccum.

An empty space - or a space that has a reasonable low density of matter. For example, if an enclosed space contains air and you pump most of it out, so that the pressure is much lower than the surrounding air, it could be called a vacuum.
