The noise from a gun firing is particularly detrimental to the human ear, the reason for which is the fact that gunshot noise typically resides in the 2-3 kHz range. Statistics for the Decibel (Loudness) Comparison Chart were taken from a study by Marshall Chasin, M.Sc., Aud(C), FAAA, Centre for Human Performance & Health, Ontario, Canada. The same goes for the popular AR-15 sporting carbine. Any exposure to decibel levels at or above 140 dB can … We’ll touch on how silencers work, how noise is measured, and what safe limits are for noise exposure. Or 1 Bel.

There was also a greater range, from 152.4dB to 164.5dB, representing 12 dB difference, or more than 10 time as much acoustic energy for the top end of the pistol spectrum. If you look at our gun silencer decibel chart, you see that every time you use a silencer, you reduce the actual sound to hearing safe levels.
