SCOUT REPORT

SilencerScout Sound Test

Our core performance metric. If this is your first time exploring our data, read our sound metering methodology to understand what these numbers are telling you. Every configuration is metered at two positions and both are shown side by side: SE (shooter's ear) and ML (muzzle, left side). Metered July 22, 2026.

A gunshot recorded on a sound meter is a pressure curve that spikes and decays over milliseconds. Peak decibels captures only the tallest point on that curve, ignoring how long the pressure stays elevated and which frequencies carry the energy. LIAeq100ms takes the whole curve, applies an A-weighting filter to approximate how the human ear responds across frequencies, then integrates the impulse energy over a fixed 100-millisecond window. The result is a single number: the level of a steady, continuous sound that would deliver the same A-weighted energy to your ear. LIAeq100ms is our leading metric. Peak decibels and impulse are shown alongside it for context.

About the Test Platform

Suppressors are tested across a full range of barrel lengths and gas systems. See our article on the test platforms for full detail behind our test configurations.

The AR-15 hosts behind our 5.56 tests — write-up not yet published.

First Round Pop

On the first shot, unburnt propellant mixes with the oxygen sitting inside the suppressor and burns a second time in the can. That secondary combustion often makes the round louder than the ones behind it. Once that oxygen is burnt off, follow-up shots settle into a quieter, steadier number. This is commonly called first round pop, or FRP. Because a hunter, marksman or defensive shooter may only ever fire one or two rounds, we isolate the first-round data rather than bury it in the average, and present it here. The magnitude of first round pop varies substantially across designs.

Backpressure

How much a suppressor extends the pressure event inside the barrel and operating system. Higher means more gas driven back at the shooter and the action, increasing blowback and wear on your firearm.

Efficiency Metrics

These metrics nest raw decibel performance in the important context of how well a suppressor performs for its size.

Quoted off 14.5" AR-15 · 5.56 Lake City M193. Each value is dB reduction ÷ the listed dimension, at shooter's ear (SE) and muzzle left (ML).

Tuning overhead

This metric captures the tuning overhead of the suppressor when paired with sound-mitigating part choices. A valuable metric for understanding what overhead you, the end user, have to push the performance envelope. Both rows are the same barrel and the same load. Only the parts used change.
