How high can you go?

[holly_evolving]

In case you didn't get to try it the first time around, this site provides a range of mp3 files to test how high your hearing is. Most people over 25 can't hear past 15khz. That's the highest frequency on the list for me, for example.

Watch it if you've got pets in the room - the noise is piercing, even if you don't play it loud.
