If you really want to find out exactly how loud your bow is, I have found two ways that work well. I either enlist the help of a friend or relative to shoot my bow while I stand 20 yards or so away and listen to exactly how loud it is. You could also have him shoot it from inside the blind, because there is a chance that the sound is actually being muffled by the blind. If you can't find someone to shoot your bow, you can go and set your video camera on a tripod and tape it. This way you can listen to it when you are done shooting and find out how loud itreally is.
