[Closed] Can anyone else 'hear' ultrasonic sound emitters?

Every few years I go for a medical which includes hearing test. Every time I am complimented on my hearing ability and the doctor doing the test gets all excited about it, as if it is something I have somehow managed to achieve off my own back. I can apparently pick up things at the extremes of human ability. I can hear all sorts of buzzing and high pitched things day to day that no one else seems to be able to. I didn't find out about this until well into adulthood, perhaps if I had known about it when in my youth, when your hearing is better, I could have done something useful with it.
