Home Forums Hunting & Shooting AR and Tactical Rifles Best noise reducing compensator?

Here's a video with a blast shield (similar to the Noveske pig and KAK device) and a decibel meter. The decibel testing starts around 4:30.

They obviously push the concussion forward rather than to the side, but to say that they are quieter is very misleading. The Griffin blast shield reduced the noise at the muzzle from 170ish to 166ish decibels.

For reference, a whisper and rustling leaves are rated at 20 decibels. So the blast shields reduce the decibels by 1/4 of the sound of rustling leaves.
