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?

    But that pressure is still there pushing against your eardrum

    So what you’re telling me is, i should really be wearing hearing protection when i go underwater? All that pressure must be wreaking havoc on my hearing.
