Just a while ago I was in a sheltered carpark and I think there are some ground hacking work using those jackhammer. The carpark is not basement (not enclosed) but it is sheltered with opening at the perimeter (without walls but just beams). I am somewhere behind the a couple of walls from the works (no direct line of sight from the sound source) though I not sure where it is but I believe it is not very near based on the sound level. The sound level is not those that are very loud (not those that would instantly remind me that it is dangerous and to hide and cover my ears) but it is considered quite loud. I was there only for about 4 minutes.
Getting a bit paranoid. Very worried if it will worsen my T as recently my T have been improving.
