I believe that the DB rating is going to be the same. The brake redirects the sound more to the sides instead of allowing it to travel forward away from the shooter. I have only been around one gun during hunting season that had a brake and after we were done shooting I came to the conclusion that would be the last gun with a brake I would ever be around. I don't understand the fascination with brakes, unless you are shooting a 50 cal or maybe a 460 weatherby.
