Why the Lowest Decibel Number Is the Wrong Way to Pick a Suppressor

If you're shopping for a suppressor by scanning spec sheets for the biggest decibel-reduction number, TFB TV says you're doing it wrong. In a video from TFB TV, James Reeves sits down with B&T's Sebastian Enzler to break down why that single number is a lot less meaningful than most buyers assume.

Key points

• Numbers aren't apples to apples. Enzler explains that decibel reduction changes with the host gun, barrel length, ammo, and even where the microphone sits, so a figure measured on one setup won't hold on another.
• Short barrels skew results. The same .22 suppressor can show a modest reduction on a 16-inch rifle but a much bigger one on a short pistol, simply because the pistol starts out louder.
• Back pressure is the real frontier. B&T's reduced back pressure (RBS) design vents gas early, which Enzler calls one of the biggest suppressor advances in over a century, cutting port pop at the ear even though it can measure louder at the muzzle.
• Two measurements, two stories. Muzzle readings and shooter's-ear readings often disagree, so a can that looks loud on paper may still be quieter where it counts for the shooter.
• Old data is suspect. Enzler notes that early suppressor testing used equipment too slow to capture a full gunshot, meaning decades-old decibel claims were often understated.

Quick take

The video's argument is straightforward: a suppressor is a system of tradeoffs, not a scoreboard. TFB TV makes the case that buyers should weigh back pressure, port pop, and intended use alongside sound numbers instead of chasing the lowest decibel figure on a chart.
