Thread: Suppressor sound testing

Hi All,

We have started to do a few suppressor sound tests this week with the proper sound equipment (B&K 2209 with 4136 mic) using a factory Rem 700 308 sps, 24” with factory Winchester 150gr power point.

Our standard over barrel suppressor with four baffles gives an average sound reduction of 21.92db Additional baffles give 1 to 2db sound reduction each, we tested up to 9 baffles that gave us an average reduction of 31.20db

One of the test we thought would be fun was to try something we read in the book by Al Paulson: Suppressors ,history and performances volume one, on how to rig a suppressor test by using a liquid medium inside the suppressor to absorb some of the energy of the shot. (this reduced the first shot by nearly 8db more than a dry suppressor)
