SSS.6.56 - Research Supplement: The Quietest 308 Rifle Silencers - Detailed Sound Comparison (Members Only)
/
Four silencers evaluated by PEW Science are included in this members-only Research Supplement to examine relative First Round Pop (FRP) and overall sound signature suppression performance characteristics. The silencers in this group were selected for their high sound suppression performance; silencers maximizing their PEW Science Suppression Rating on a supersonic centerfire bolt action rifle. Silencers with suppression performance in this range typically have relatively high flow restriction, or back pressure, characterized by a relatively high PEW Science Omega Back Pressure Metric.
This research supplement is intended to provide more information to PEW Science members with regard to specific sound signature characteristics of the tested configurations in the aforementioned reviews and to help frame objective loudness comparisons between the four quietest supersonic 308 rifle silencers in the FRP and total sound signature suppression regimes. This supplement is part of ongoing PEW Science small arm weapon system sound signature research.
