OMG, that second file...I heard it right away and it was terrible.

I tried both links on the sweep page. The top one I heard right away at 22, and the bottom one I heard right after the announcer said 22. Both incredibly horrible noises.

My front door is being painted, which means some guy was just party to me playing and replaying noise. Or perhaps he couldn't hear it...

Did you use the top version? The bottom one I heard right away, but not the top one.

Okay, weird. I had saved the top file, and when I play it from my hard drive, I hear it right away. When I play it in the browser, I hear it at 20.

Everyone is totally fascinated by my ears, right?

I'm 40 and I heard the noise... but the jewelry store in the mall that used to drive me nuts when I was a kid stopped bugging me when I was in my twenties.

Huh. With the second file, I heard it starting at 22k. It was all crackly, but I could hear it.

There's a low frequency one too, but from the text it appears that it's more of a test of my speakers than my ears, which appears to be true. My laptop speakers start the low one at 100Hz, but with my house in-ceiling speakers plugged into my laptop output, I can hear it right at the start at 10.

With the high frequency one, I hear it at the same point regardless of the speaker. I am finding everyone's results fascinating. It's making me want to do up a chart with ages and genders and hearing range.

Of course lots of things make me want to do up a chart.

That makes me think of this:

Also, now that I have it linked through the system, it turns out Seabiscuit can hear it as soon as it starts and DOES NOT WANT. Heheh.

The sounds have this "warning" which applies to my work computer sound card:

Beware: cheap sound cards may have trouble reproducing the highest frequencies of this test. At best, they won't reproduce anything. At worst, ghost frequencies will be generated in the audible range. These frequencies are not representative of the file's contents! If you hear strange ups and downs or anything else that does not sound like a continuously descending sweep, suspect this test to be corrupted by aliasing (the scientific name to this phenomenon).

So I can't take the test on this computer.

I tried it on a different machine, and I think I got real results, aka I can't hear it until 14 or 15.
