OSHA reference (29 CFR 1910.95): Chart lines show the 85 dBA action level (1910.95(c)(1)–(c)(2)) and selected Table G-16 permissible noise exposures (dBA, slow response): 90 (8 h), 95 (4 h), 100 (2 h), 105 (1 h), and 115 (¼ h or less). These are workplace time-weighted / continuous exposure criteria for comparison against the calculator’s inverse-square SPL estimate — not a hearing-safety certification.

These figures are compiled estimates from Thunder Beast Arms Silencer Summit measurements for comparison only. They are not lab-certified hearing-safety ratings. Hosts, ammo, and conditions differ; do not treat displayed SPL as a guarantee of hearing protection.
