I have to agree. I really like all the new sounds (including the now very definitely audible and alerting alert sound). Sound levels could possibly be adjusted for some, though I kind of like that belts (especially yellow ones) are really quiet. The sounds of the laser turrets working is also nifty. But the laser firing sounds, not so much. The various gun firing noises are enough to make me give up on the weapon and artillery sounds mods I have.
I sort of wonder what a really powerful continuous laser sounds like. I would bet that it makes a loud crack sound when it first comes on and then doesn't sound like anything. I don't know that realism in this regard would make the game better though.
