Custom Hearing Protection for Shooting

How Many dB is a Gunshot?

Decibel levels for firearms average between 140 and 165 dB.

The following is the best researched compilation I have seen measuring the sound level of different firearms. Sound pressure levels are measured 1 meter to the side of the firearm. Bear in mind that sound levels above 85 dB can cause damage; above 140 dB can cause IMMEDIATE damage.
