  1. Wow. I could kinda-sorta hear something at 17.7, but no higher.

  2. I once bemused a biology TA in my first year of uni by requesting that he *please* turn the video monitor fully off, not just leave it on standby, because the high-pitched hum was too distracting for me during the prac class. He complied, rather quizzically.

    About 10 minutes later I heard the hum again and caught him standing watching me to see whether I had noticed him turn the video monitor back on i.e testing whether I really could hear something. He had the grace to blush when I raised an eyebrow at him emphatically.

  3. I max out at 10. My ears must be old.

  4. Both Rob and I could hear the 21.1kHz without any problems.
    The last one we couldn’t hear. Its like being 20 all over again.
    The 8kHz nearly made my ears bleed.

  5. I tried again. I can just hear the 22.4kHz, just but its there.

  6. At home with the tv off and the sound turned up I can hear up to 18 but it is a very low hum. Interestingly my five year old just came in from outside to ask what the noise was. Very sensitive to sound.

  7. I don’t know whether my laptop speakers can emit the higher sounds, but I maxed out at 15.8, “You are in your twenties. You can still hear reasonably well and you can play this without my old fart colleagues hearing it which makes you feel kinda good.”.
    My ears are younger than I am!

  8. Only barely heard 14.9. My inner ear is a desert. *shakes fist* Curse you Sony Walkman!
