.300 Blackout suppressor sound tests

2 tests used this cartridge. Each test is one rifle, one day, one set of ammunition. Results from different tests can’t be compared with each other.

Smaller tests

2 more suppressors were measured with this cartridge. They come from 3 tests with too few suppressors on the gun to be worth comparing: with two or three, finishing first says very little. They are listed here instead.

.300 Blackout subsonic, 16" bolt-action rifle2025

85 suppressors were fired on this same gun, on the same day, with the same ammunition. Fired with no suppressor at all, it measured 149.7 dB, which is what each reduction below is counted from.

The bar above the list places each of the 85 suppressors fired on this gun by how loud the shot still measured at the shooter's ear. Between the quietest and the loudest there is 25 dB. It stays on screen as you read, so hovering a row shows where that suppressor falls.

The shaded band is the tightest 1.9 dB stretch of this strip, holding 16 of the 85 suppressors tested, which this test cannot tell apart from one another. It is a sample rather than a special group, so sweep the strip and the band follows. No 1.9 dB stretch of this strip holds more of them than that, so the field really is spread out: on this gun, which suppressor you fit changes how loud the shot is.

Products come and go from these events voluntarily. A suppressor missing from this list was not tested, nothing more. Differences smaller than 1.9 dB are closer than this test can reliably measure. The results also don’t record which mount or muzzle device each suppressor was fitted with, and that hardware can affect both the reading and the weight and length shown above. Decibels are not a count of anything: as a rule of thumb every 10 dB is roughly a halving of how loud something seems, so the gaps here are larger than they look.

Every row opens to show all three microphones, and it is worth opening. A suppressor can be the quietest here beside the muzzle and middling at the shooter’s ear, so a claim about one says nothing about the other.

Thunder Beast published the decibel figures, the weights and the lengths. The resolution limit of 1.9 dB, the shaded band, and the 149.7 dB unsuppressed figure are worked out here from those measurements.
