Inigo always said I had dog hearing, but....

......this was ridiculous!

One of my coworkers got a new iPhone. He's been downloading lots of free apps, having fun with it. He was demonstrating it to some of my coworkers, several cubes away from mine. All I hear is this high-pitched electronic noise. I thought my monitor was going. It stopped and started up again. Apparently, the app he was demonstrating was some annoying noise app. He was demonstrating the dog whistle.

What makes it even worse is that I started walking down towards the cube they were in, and asked if they were making some high pitched noise. One of them told me that it was a dog whistle. I just looked at her, and she realized what she said. :)

Still, they couldn't believe that I could hear it.

That's not what he said. He said you were...never mind. :p

My hearing is gone in those frequencies. There is an online site that lets you play different pitches, and the high ones, I could not hear, but the kids would complain, from the second story, about the annoying noise.

ETA: Here (http://www.jimmyr.com/blog/hearingloss.html)is one. I top out around 15. My kids go to 19. Using my computer speakers, so this is not totally reliable. Dog whistles are between 16 and 22.

I topped out at 20, does that mean I can hear dog whistles also?

[eddyj]

Yes you can, you dog, you!

The mosquito ring-tone (http://www.freemosquitoringtones.org/) is a good one too.
Maybe a 22khz

It's not surprising that Agatha can hear dog whistles, since she no doubt has had plenty of experience hearing wolf whistles. :)

My son has creepy hearing. If I turn on the TV, he comes from the other end of the house and asks what I'm doing. And he's not hearing sound from the speakers -- doesn't matter if the sound is muted, or if the TV is on an input without sound coming in. He can apparently hear the "pop" of it turning on, and some electrical hum far outside my hearing.

A friend of mine is the son of classical musicians. His hearing is otherworldly. In physics class in high school, the teacher set up a wave generator with a sound amplifier. He had us all raise our hands, then put them down as he went up the scale of human hearing. My friend's hand was the last one up, and for a good long while.


ETA: I tried the app linked above. My hearing tops out at 13-14khz. But then I've been to a lot of rock concerts, and a drove a convertible for eight years.

I can hear 17k but not 18k.

I could hear the high-pitched whine it emitted anywhere in the house. I lost the ability to hear such high frequencies in my 30s.

I installed the mosquito ring-tone on my iPhone and we were playing with it at lunch one day. The kids and I could hear it and my wife couldn't. She thought we were lying. I ended up having to have the kids and me cover our eyes while she started it randomly, and we raised our hands when we heard it.

I can just barely hear the 14kHz tone. I blame my nemesis, the aging process -- because I don't want to blame my iPod.

[dcheesi]

I barely hear 13khz :(

In addition to the requisite rock concerts, I also inherited issues from my father. Neither of us have ever been able to hear well in noisy environments, which may indicate that our top frequency was never that high to begin with.
