Depends from signal strength and receiver amplifiers.
Ah, well there's the thing, isn't it? It's sounds that are actually audible to the human ear, as in space ship whooshy noises in game or movies. I don't want to find out by personal experimentation but I'm guessing most people couldn't hear a wave travelling through a medium of a hundred or so atoms per cubic metre.

A far more greater problem would be that an atom colliding with a fast travelling ship == a ship colliding with a fast travelling atom.
Mass effect fields, mate.
Everything's solved by mass effect fields. Hostile wepons? Mass effect fields. Artificial gravity? Mass effect fields. Spaceship engines? Mass effect fields. Lost the ignition key for the Normandy and got locked out on Ilium? Get yourself a couple of mass effect fields and rub them together, and the central locking just pops right up.... probably. Doesn't need to make sense, just mass effect fields. Fixes any problem apart from Mess Sgt Gardner's cooking.
