Estimate likely peak impulse-noise ranges and view conservative hearing-risk guidance.
Estimated peak impulse noise
160-167 dB
Estimates only. Do not rely on this output for safety decisions.
Load profile: 62gr (M855)
This estimate sits in impulse-noise levels that are commonly cited as potentially harmful. Use proper hearing protection and avoid treating any setup as safe by default.
Use proper hearing protection and review muzzle blast tradeoffs before making setup decisions.
Table shows estimated peak impulse ranges by barrel bucket for the selected caliber, environment, muzzle setup category, and load profile. Load is treated as a secondary modifier versus environment and muzzle setup.
Model inputs and effects: barrel bucket applies a primary length adjustment, environment applies an indoor/outdoor adjustment, muzzle setup applies the largest category adjustment (including suppressed), and load applies a smaller caliber-specific modifier.
These are broad range estimates, not instrumented measurements for a specific firearm or ammo lot.
| Barrel bucket | Estimated peak range |
|---|---|
| 10.5 in and under | 165-172 dB |
| 11.5 to 12.5 in | 163-170 dB |
| 13.7 to 14.5 in | 162-169 dB |
| 16 in | 160-167 dB |
| 18 in and over | 159-166 dB |
