Hearing a 20 Hz frequency is weird too. I have trouble imagining a membrane moving at 20 cycles per seconds and hearing a continuous sound out of that.

Oh I know what you are talking about! Haha, it used to annoy me in my small campus room when my focus shifted and made me start hearing my router communicating wirelessly with my laptop computer: an intermittent, high frequency tone, but very low and insidious and once you have set your attention on it it's very hard to "forget" it is present!
Now I have moved and the fridge I have makes more noise and overall it's more noisy (well, from a silent low dB to another silent low dB, because I love to do my homework in silence and I make sure I have it when I need it) and I don't know, but I don't hear it as much anymore.
Gosh it annoyed me in my first semester.

exactly. i been trying to say that. people think they can hear 21khz in these test but they really can't. it's just harmonics. it's not actually fundamental 21khz tone. that's why these tests people try are not legit. no one wants to listen so let them believe what they want. i bet barely anyone around hear can hear electronics around their house. lot of monitors,modems and tv's give off a fundamental 16khz tone when on standby or turned on first time of the day. can people hear their monitor or modem when they walk by it? probably most likely not. i get annoyed with my modem and still hear it from upstairs.
