I like handwaving, so let me make an excuse for *Pirates* here.
Actually, two of them. The first excuse is that a certain amount
of noise might come through contact with the hull and thus with
hull vibrations caused by the various machinery operating. But
that's probably not good enough.

The second excuse is that everyone was in what we're told are very
automated spacesuits, in an environment with fairly smart computers.
People notice and react to sound cues. Thus, there is a good case
for generating entirely artificial in-suit noises that correspond to
important things going on in the outside world, things like airlock
doors opening or potentially dangerous mechanisms in operation that
you should steer clear of. So far all of the noises in space we've
heard in *Pirates* have been noises from the ship itself, things
that could plausibly be faked in the suits for this reason.

(By the way, I understand why shows love their sliding airlocks but
I think it's a stupid design. As I picked up long ago from reading
Heinlein juveniles, in theory the safest airlock door is one that opens
inwards because then it's essentially impossible to accidentally open it
until the inside has been depressurized. If the inside is still under
pressure, you have many pounds per square inch holding the door very
firmly closed. But inwards-opening doors would not make for good staging
and good scenes, so we have the kind of sliding ones that we see in
*Pirates*. This has been your digression of the day.)
