What is the absolute max level of ear protection you can get?
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?

Offline open source AI pointed me to this article on Wikipedia:
Electronic hearing protection devices
Some HPDs reduce the sound reaching the eardrum through a combination of electronic and structural components. Electronic HPDs are available in both earmuff and custom earplug styles. Electronic microphones, circuitry, and receivers perform active noise reduction, also known as noise-cancelling, in which a signal that is 180-degrees out-of-phase of the noise is presented, which in theory cancels the noise.[1]
Do you know what the rated NRR is? The Wikipedia article doesn’t say so this doesn’t really answer the question.
It points you in a new direction of research and information like any others here. Sorry I cared to ask and respond I certainly won't next time.
Thing is, you didn't care to respond. You let an AI respond for you cause you wanted to comment despite having nothing to say on the subject.
I did not. Read it. It is a quote from the article after I verified the reference. It is a toxic bias of group think fools that take no time to read past what they want to see.
It seems like your response was either trying to waste my time by sending me down a rabbit hole to find the information you didn't provide, or just being lazy and not caring to so much as check what you were posting. In either case i could do without responses like that cluttering my limited time.
I a person. I spoke in good faith. I quoted a wiki reference.
Sorry, you're right, i was being too harsh. when i responded i thought you weren't speaking in good faith, but i must've misinterpreted.
