I want to try a experiment with frequencies. I will post a sound file that produces a Sin Tone with a freq at 17000Hz. I want you to post if you hear it or not, and your age. My hypothesis is that older people will not be able to hear the sound. Link to it is:

You need WinRAR to extract the file
Forgot to mention, I am 16, and can hear it easily.
