// The Silencer Sound Standard™

The commercial industry standard

Eight components, from foundational acoustics to the maps and rankings you actually use. Built on measured gunshots, not marketing.

SSS.1

Foundations

Scope, definitions, and the questions the standard exists to answer.

SSS.2

Real Gunshot Analysis

Empirical measurement of actual gunshots, not theoretical models or estimates.

SSS.3

Physiological Effects

How suppressed and unsuppressed shots actually affect human hearing.

SSS.4

Test Methods & Results

The repeatable procedure and the raw acoustic results it produces.

SSS.5

The Rating System

How measured data becomes the Suppression Rating™ you can compare.

SSS.6

Sound Signature Reviews

Full per-configuration reviews of a silencer on a real host and cartridge.

SSS.7

Hearing Damage Level

Translating the signature into a clear hearing-safety verdict for your use.

SSS.8

Hazard Maps

PEW-SOFT™ free-field blast-hazard maps of the space around the shooter.

// Sound Signature Reviews™

Every silencer, on real hosts

Each review pairs a measured Suppression Rating™ with a PEW-SOFT™ free-field hazard map, on the exact host and cartridge that matter. New deliverables drop constantly, alongside the Jay Situation podcast.

// How every review is built

From gunshot to Suppression Rating

The same repeatable method on every silencer. No shortcuts, no estimates.

1

Acquire the hardware

The silencer, host weapon, and ammunition are sourced and documented for the exact configuration under test.

2

Real gunshot analysis

Live fire is captured on calibrated, high-fidelity instrumentation, the actual pressure signature, not a model.

3

PEW-SOFT™ analysis

The signature becomes a Suppression Rating™ and a free-field blast-hazard map of the space around the shooter.

4

Publish the review

The full Sound Signature Review goes live for members, alongside a Jay Situation podcast breakdown.

// Independent by design

Nobody buys their way onto this chart.

The value of a Suppression Rating™ is only as good as its independence. So the rule at PEW Science is simple and absolute: no silencer manufacturer or third party has influenced or controlled anything published on this website. The findings come from measured gunshots and a documented, trademarked standard, so every silencer is judged the same way, on the data alone.

That independence is funded by members, not sponsors. Basic Suppression Ratings stay free; membership unlocks the full reviews, the hazard maps, and the sortable comparison tool.

  • Zero manufacturer or third-party influence
  • Empirical gunshot analysis, never estimates
  • One repeatable method on every silencer
  • Basic Suppression Ratings always free
