How Loud are Un-moderated Firearms?

Firearms are loud! Un-moderated sound levels from firearms have been proven to be highly damaging to hearing regardless of the amount of traditional hearing protection used. The average full bore rifle creates a sound wave between 165 and 170 dB. Most hearing protection offered on the market reduces this sound by 15 to 25 dB. This means the sound reaching the ear during each gunshot can easily be between 140 and 155 dB while wearing hearing protection. Many hunters regularly hunt, for safety reasons, with no hearing protection at all. The universally recognized threshold at which hearing damage is guaranteed is 140 dB. The ability of a sound moderator to reduce the report of a firearm varies widely but a 35 dB reduction on a hunting firearm is a good average for commercially available sound moderators. This reduction would make firearms much safer, by reducing them to a safe sound level comparable to a large jackhammer. Hunters and sport shooters in Canada are losing their hearing and they need access to all of the safety equipment available to prevent this.
