It has been used as a deterrent device to keep teenagers from loitering in malls and shops, and sounds similar to a buzzing mosquito. Typically the longer you listen to it, the more annoying it gets.

  1. To my surprise, I could. One ear more than the other, but not the ear I expected. Now I'm trying to figure out what software on my work computer can display a waveform so I can, yanno, look at it. like ya do.

  2. Nice Mer!
    I'm amazed I still can after all the concerts and clubs I went to when I was younger...

    I give myself pretty regular hearing tests using the simple synthesis tone generator in Sound Forge.
    Fire up any tone generator, use a sine wave, and crank it to about 17Khz. That's the mosquito.

    I hear almost 18K in one ear, and just over 16K in the other.

  3. Yep, I can hear it in my right ear. My left ear now gets tinnitus at about this frequency after some problems related to medication a few years back, and some of the top end has gone, unfortunately.

  4. Nice "gobs".

    Good ears help quite a bit in our line of work.

    Or at least good *ear* anyway...

  5. I could hear it YUY!! I hope that means my ears are still prefect. :)

  6. Congrats 80!

    Now make sure you keep them that way!
