Suppressor sound tests / .308 / .308, 20" bolt-action rifle

.308, 20" bolt-action rifle2025

70 suppressors were fired on this same gun, with the same ammunition. It was not fired without a suppressor in 2025. At the 2024 Summit, the same gun with the same ammunition and no suppressor measured 155.9 dB, and each reduction below is counted from that 2024 figure.

The bar above the list places each of the 70 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 24 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 17 of the 70 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. Names are shown as Thunder Beast listed them. A name without a link doesn’t have a page on Baffled yet. 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 155.9 dB unsuppressed figure are worked out here from those measurements.

The 155.9 dB unsuppressed figure is from the 2024 SILENCER SUMMIT, published by Thunder Beast Arms Corp. See their 2024 results
