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?

    I know nothing about this subject, but my instinct would tell me that anc would actually be protective. If you phase out sound, it seizes ceases to exist, right? That is the whole point of it?

    Again, pure instincts, don’t know shit myself.

      *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.
