Further to earlier replies; actually, sound will propagate in space (particularly in dense nebulae) providing the sound is low enough. (The shortest wavelength, and hence the highest note, of sound that can be transmitted is some multiple of the mean free path - very roughly, the average distance between molecules of the gas.)
Scientists have detected (by indirect means) a sound wave 57 octaves below middle C, in a nebula near a galactic core. Link:
Black hole produces deepest ever note
Naturally, the sounds in space will be inaudible to anything with an eardrum less than a few AU across.

The density of the space in between planets is too low to support 'sound,' as we think of it.
Suppose you jettision a loudspeaker from a space station: what is there for it to vibrate against? Sure, the occasional stray particle might be given some momentum, but there's not enough to "capture" the whole thing coherently.
If you create an explosion, there will be initially, but I'm guessing the molecules will quickly diffuse out into the surround space (thanks to all of the internal collisions going on).

You need a medium for sound..just like sound can travel through water, it needs something to travel through. Since space is mostly empty, there's not much top travel through.
*SIGH*
Contrary to public opinion, space is NOT empty. The sun is constantly emitting solar wind, which has a sorts of "sound" to it. Certain satellites are designed to listen to this sound, and they use it to predict certain solar events, like Coronal Mass Ejections or solar flares. The only places that can be considered truly empty is the deep space between star systems. And even there you supposedly can find the occasional atom or two every once in awhile.

Totally off the topic, but since we are talking about medium...
Can we see Laser beams in space like star wars laser stuff?

no **** sherlock. really? ya think?
notice that part where he said ther isn't much to travel through (not that there isn't anything what-so-ever)
the ability for waves to pass through space that may have "a sorts of 'sound' to it." it hardly the same thing as there being able to hear sound in space. i dont care if your are in a nebula or kickup up dust on the moon, you aren't going to hear jack even if a stick of dynamite goes off 5 ft away from you.
