@Samir I question that everyday, where was the "danger sign"??
They started that loud machine out of nowhere. I couldn't see anyone, and this happened on the weekend so I thought that no one was there. I think they stood pretty close to were I was walking, maybe just a few meters away. There were a lot of people passing this tunnel, including a friend of mine and her daughter.
It wasn't even my stupid idea to walk down in the tunnel in the first place. It was my friend's idea and she didn't even developed tinnitus, and I hardly believe anyone else did except me.
I never had any problems with my ears before this happened
It's like I died that day. All my dreams got flushed away.
