Sound in space is sometimes handwaved by creators as something that the ship's computer creates for the benefit of the pilots. I can buy that, I suppose...

Wait, what?

Basically, if someone farts outside the Millennium Falcon in space, the onboard computer will simulate the sound of a fart so that it will appear that the guy's fart in making noise through the hull of the ship, even though there really is no fart sound passing through the vacuum of space.

Frankly, it's a stupid explanation, just like "relativistic shielding".
