I was taking a nap while wearing 33 dB NRR earplugs, when all of a sudden what sounded like hammer sounds coming from the outside of the wall of my room wake me up for a few seconds, then It keeps happening for 30 more seconds, then I went out side, and my landlord was literally outside of the house, operating a nail gun, and I tell him to stop. I slept for 10 hours woke up and my right ear kind of hurts, would the nail gun do permanent damage to my ears?
