Something to keep in mind is that our species contains LOTS of genetic diversity. So you'll find that NOT all people have the same sensory range.
True story: Back in my college days, while doing an internship at a museum , I walked in one morning and just about lost my eardrums. VERY intense sound that hit as soon as I'd entered one room (in the staff/research area of the museum). It turned out that they had an ultrasonic security system, the alarm for which could be turned off seperately & which was located in a more convienient location. So... sometimes the first ones in turned off the alarm, but didn't remember to turn off the security system itself. None of the staff could hear the ultrasonic waves used to detect intruders, so they never noticed whether it was off or not, but perhaps once a year some hapless visitor would have the same unpleasant experiance I had.
I've also heard of occasional people whose range extended further down into the sub-sonic range than usual.
It makes me wonder just how many people have the extreme ranges (& how much it's turned up in testing, especially if rare), and whether certain animal species such as dogs have similar rare individuals with extended sensory ranges?
BTW, how many people here can hear bats' echolocation? My family all can, but most people I've met can't (I've asked folk while on evening walks, with the bats all around us).
