Just because air is not present to be moved, Im not at all convinced that the sound just doesnt exist and its properties could not be measured.
Infact without air to "vibrate" would the properties of sound be effected or just remain in audible to the human ear?

If your question is really in a vacuum then no. If, however, you mean in space, then yes, it can. See http://www.nasa.gov/centers/goddard/universe/black_hole_sound.html.
Excerpt: "You may be wondering how a sound wave can travel through space. After all, sound waves require some sort of stuff to move through. This stuff, called a medium, can be air, water, or even solid rock. And space is thought of as lacking any medium because it is a vacuum.
In fact, space is not a pure vacuum but rather it contains stray bits of stuff -- gas atoms and dust of varying amounts. In the case of the Perseus cluster, the gas throughout it serves as the medium through which the sound waves coming from the central black hole travel."

Sound is caused by vibration of matter. When the vibrations pass through different types of matter, the sound changes. For example, because water molecules do not vibrate as efficiently as molecules in the air do, we do not hear sound underwater as well as we do on land.
In a vacuum, there is no matter to vibrate, therefore, sound does not exist at all and there is no way to produce or detect it.

In space, no one can hear you scream!
Sound is another form of energy, this energy is carried in sound waves via atoms in the air. Nothing to carry to the energy implies no sound.

not the way we perceive sound. Sound is Dependant on air to be heard

Sound needs a medium to propogate. If it doens't propogate in the first place, how are you going to measure it?

probably yes, if there's an object that's vibrating in it. we just can't hear it because there's nothing to carry the vibrations to our ears.

sound is a result of waves of air hence no air no sound
