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?

    There was that Nathan For You episode where they locked that kid in a coffin and had an orgy outside to test the sound proofing. No real practical use but apparently it did a good job.

    All jokes aside, I’m very interested to hear if something exists to that degree of practical hearing protection. Maybe a "suit"of sorts to cancel noise and dampen bone conduction or super active noise cancelling?

      You just named a practical use.

      You’d need the suit to allow you to “float” inside or it. Air gapped, and rubber suspension? Maybe some kind of a liquid, but it would probably just allow for more transference?
