Many years ago, and I know I’ve put this story in a very old thread here somewhere, I had a real problem because I could hear decibels that other people apparently can not hear. It caused me MUCH pain in some stores I went in to shop. One in particular was excruciating; the sound was VERY high and very loud and felt like hot lazers through my ears and head. I’d even tried covering my ears but it didn’t help. I could tell specific ‘hot spots’ and avoided them.
One day, for whatever reason, the person I was with wanted to see something in that area. with the worst hotspot I tried to dodge down isles further from the area. I was covering my ears and literally jogging down the isle telling my companion that the noise was too loud and I just needed to get further from it.
Suddenly the store manager was chasing after me hooting ‘stop, please wait I want to ask you something!‘ I was not a criminal, just in pain so I stopped and turned when the manager asked, ‘tell me what you hear’. I explained and he advised that when the alarm system had been put in they’d been told that on rare instances people may react to the hum but typically it was so far beyond human ability.
I think that more people DO ‘hear’ but don’t identify that their discomfort IS coming from decibels; they may think it’s something vibrating through another part of their body.
