Those taser rounds are actually subsonic, so the loudest thing will be the action cycling, not the crack you would get from supersonic ammunition that has been suppressed. The action cycling isn't THAT loud (speaking from experience) on a gun that has been tuned for subsonic ammo. If you happen to have a semi-auto shotgun handy, lock back the bolt and then hit the bolt release. It's noticeably softer than that, since the springs are weaker to account for the lower recoil.

the ammo going supersonic isnt the only loud thing. bullets are propelled by gunpowder, which is basically an explosive. that is loud too, even if slower bullets require less gunpowder.

unless taser rounds are something completely different and you mean something closer to an actual taser. though that would create its own set of problems, like the inability to taser more than one person at a time, with a "cooldown" of a few seconds between shots.
