Some may not agree with this but hear it is.
While doing brake testing for the quietest brake, we discovered something that went against all that i believed and had heard for years. In our test we used a DB Meter and tried as Many brands as we could and all of the different styles. Our goal was to find out what design was the quietest design.
We placed the DB Meter near the muzzle (3' to the side and out of the bullets path) to get the DBs at this point . we then moved the meter to the side (90o to the bore center). Then we moved the meter 3' behind the shooter.
Each test was with the same rifle and ammo and was conducted with a brake and without one for a comparison.
The loudest DB reading was out front of the rifle without a brake. The quietest reading was with a brake, and interestingly enough, the better the brake was at reducing recoil, the lower the reading on the meter. from this we Deducted/speculated that when a muzzle brake does its job well it brakes the sound into parts of sound that divide up the total effect of one major blast of sound (It redistributes the total amount) what ever it was, the DB Meter did not know what we were going to do so It recorded what It heard.
What we did find was that the position of the bystander effected the perceived sound to the person, and He could tell where and when he felt and heard more or less sound.
When we backed off and allowed the DB meter to sample the total sound It remained very constant for all test (It was measuring total sound produced by the firearm.
So to sum it up, Brakes redirect the sound and muzzle blast, but don't make the sound level increase. The shooter or a bystander receives a larger portion of the total sound emitted by the firearm and there fore "Perceives" that is louder. To him It Is, To the meter It is not.
Irregardless of all this data. NONE OF THE READINGS WERE SAFE LEVELS FOR THE EAR. The lowest reading the meter recorded was 105 DB, the highest was 108 DB. the range is way above what the ear can handle and ear protection should be used under any circumstance when firing a firearm because even though you don't notice it when hunting, the damage is still being done.
If you use a brake or not there will be damage to your ears if you don't wear some type of hearing protection.
These test convinced me (I hunted most of my life without hearing protection) that It was necessary to save what I had left i had to faithfully wear something to protect my hearing whether at the range or hunting.
