If I recall correctly the maximum Noise Reduction Rating (NRR) for earplugs and earmuffs is around 30db. You can combine the two for a slight increase in hearing protection but you still hit a limit because of bone vibration.
Is there PPE out there to go even further beyond this? Where would it be commonly used?
*ceases, FYI (not being snarky, maybe autoincorrect got you on voice to text)
Edit: also “seizes” used here was kinda funny
Thanks for the heads up. Non-native, always willing to learn.
