OK Folks.Lets put this in perspective. I have hearing loss and I wear hearing aids. The hearing loss did not come due to muzzle brakes, it came from 30 years of small arms fire, (no muzzle brakes) heavy artillery fire (105MM and 155MM howitzers) as well as a lot of jet engine noise. Yes there is a bit of a bark from a muzzle brake and for sure definitely wear all the hearing protection you can when out on the range. I wear ear plugs plus Walker electronic hearing protection with or without a muzzle brake and shooting everything from a .22 rimfire to my 300 Mag. Keep this in mind, ear plugs and wearing a flight helmet or ear muffs did not attenuate the 120+ db noise level enough that repeated exposure over a period of time (30 years) did not take it's toll. However and I know some of you will argue, you always do...when hunting just as you don't notice the recoil of the rifle when shooting at that monster deer, elk or that big ole bear that you have ****ed off and now wants to make you dinner instead of the other way around...you won't notice the noise from one shot...oh...you missed two shots. Since it's not repeated on a constant basis in a confined area the chances of the noise damaging your hearing out in the woods, where maybe you are shooting only at 50 yards most likely will not cause the slightest bit of hearing loss as long as it is not constant. I don't know any hunters who wear hearing protection out in the field. I would rather be able to hear that deer walking around close to me than worry about something that has only an infintesimal chance of causing any injury. Since I usually only take one shot per animal, and I hope you do too nobody is going to have a major hearing loss over one or maybe two shots fired, muzzle brake or no muzzle brake out in the middle of the woods without baffles and whatever else there is between shooting points on your hometown shooting range to reflect noise back at you. If you have never shot competitively or been in combat in a fire fight you have no idea what muzzle noise is. Try shooting on a line with probably 20 others 10 feet to either side shooting at 200 or 300 yards rapid fire, or even worse when in combat in a fire fight where others are shooting at you and you have to defend yourself with idiots who do not know how to shoot firing their M-16s on full auto since they cannot selectively shoot and hit a target. Of course protect your hearing, especially on the range however keep in mind that when shooting a rifle with a muzzle brake you don't have hardly as much muzzle blast as the people on both sides of you. Be courteous and try to keep as many firing points between you and the next shooter when shooting with a rifle equipped with a muzzle brake. They will appreciate your courtesy.
