with the brake think of the sound as small sphere at the end of the gun, which grows larger surrounding the shooter and everything close (other shooters). while having no compensator it is more like an every increasing cone, widening towards the point of aim.
in long range shooting and both eyes open, it allows the shooter to "see" the smoke (discharge) emerging from the side of the rifle, which give assurance the shot was not pulled, and is "clean". This confidence allows the shooter to trust the elevation correction, and if its a miss, was probable more attributable to a "bad" wind call. In the proper light sun usually behind and over the shoulder it can also allow the shooter to see the bullet trail.
Nobody would disagree, but Im sure Stick will be along shortly to correct everybody.
