Is it part of the "overexcitabilities" --or is it a myth--to be particularly sensitive to changes in temperature, light, smell, and particularly vision (details no one in the normal range will notice) ?
I don't know about the statistics, but I have significant aural sensitivity, and some visual sensitivity too. I really can't stand the sound of my own breathing, so I tend to breath in a way that is silent... which I think increases my sensitivity to other sounds. When everything is quiet at night, I can year minor ticking or dripping sounds that are quite far away as if they were close. It's like my hearing re-calibrates to a level of sensitivity that others can't reach. I much prefer to sleep in pitch-black silence.
I have also proven my ability to discern audio differences thought to be imperceivable by many experts in the sound reproduction field, through abx testing. I have also failed to discern differences which are claimed to be easily perceptible by the manufacturers of expensive audio components. Somehow those differences that are so obvious to many in simple A/B testing tend to disappear with abx testing.
