But, since that hunt, I have worn hearing protection for everything, even shooting air rifles, and my hearing hasn't declined much more. At the range, I wear electronic muffs over plugs. On dove hunts, I wear foam earplugs. Hunting waterfowl and birds, I use those North Sonic Ear Valves, which have a mechanical valve that closes when you shoot. Some people tell you they don't work, but to me they make a real difference. With them, I can hear flushing birds yet still protect my hearing. And, on those occasions when someone thoughtlessly puts a muzzle next to my ear and shoots, I can turn calmly to them and say "Don't do that again," rather than falling to the ground in pain, clutching my ears.
