Bug Description:

Detailed steps to reproduce the bug:

1) Put 5 skill points in "From The Shadows" perk 

2) Equip Military Light Armor enhanced with advanced muffled connectors

3) Disable headlight and enable night vision googles

4) Sneak while crouching inside a room full of sleepers (for example, room full of irradiated lab technicians at the end of Pop'n'Pills Factory) and place down a loaded Robotic turret aiming at them

Actual result: Robotic turret starts firing at sleepers making a significant noise, but doesn't wake up sleepers, except for those which it directly hits

Expected result: Robotic turret actually is not a silenced weapon and produces a significant noise, which should wake up all sleepers in closed proximity, 3-5 meters radius, I guess
