Not really, provided you don't forget to properly "pop" your ears during 
decompression.

It's your eyes that might not like it, so you better close them...

The vibration of the other ship's hull would probably modulate the rate 
of gaseous emission and/or the speed of the molecules. So the sound 
might even undergo less distance-based dampening than in a denser medium.

The impedance-based dampening, however, would be pretty strong I bet.
