Scratch One More Super-Power Off the List
The news about teens being able to hear certain frequencies well below what adults can hear is nothing new. I did think it was was rather clever, using those tones as ring and text tones to avoid detection by adults. Ever wondered where your cut off point is? I did and stumbled across this site. You can play several ranges of ultrasonic tones at the following site and even download them for your own use:

I don’t think I did very well. At 15.8kHz my sensitivity cut out. After that, I can only percieve the slightest whine and even then only without distractions. After 19.9kHz I got nothing at all. To be certain you are testing yourself correctly, you should here a sharp, crisp whine, NOT a hum or static (that’s generally an audio relic of the mp3 quality). Good luck, bat-people.
You may not be able to hear high pitches, but you could still be a bat person… learn Echo-location…. http://www.popsci.com/scitech/article/2009-06/spanish-scientists-create-human-echolocation
Do you happen to have a site that will help me with my batarang aim too? 🙂
I got to 16.7 before mine kicked out. Which is strange, because I have hearing damage. I think most of my damage is on the low tones though, which is hell for trying to hear people talk (why I always want to walk behind people when I’m hiking, so I can hear them).
I wonder if its an aging gender thing, Imp. I know some elderly woman that have problems with lower tones but none at all with higher ones of the same volume.
