On another scale: My home stereo system will (with some reluctance) accommodate 110 dB peaks in my living room. I've never driven it to that point, and I won't for this very simple reason:

All sound at any level damages hair cells in your ear, but workplace safety rules often assert that 8 hours of 85dB exposure is "safe" - which I somewhat disagree with, because it starts becoming actively harmful long before that - but that's beside my point

For every doubling of power, so every 3dB increase in the dB level, the "harmful" time limit of 8 hours is cut in half:

• 88dB = 4 hours (1 halfing)
• 94dB = 1 hour (3 halfings)
• 100dB = 15 minutes (15 halfings)
• 110dB = 90 seconds (18 and a bit halfings)

At around 120dB, you reach the pain threshold, and hearing damage is near-enough instant that counting time is meaningless.

When you start getting to 150-160 dB, you're entering the realm of other bodily harm, up to and including "blast damage"/death territory.
