It's best to use headphones and listen to the warnings on the screen so as not to damage your hearing.

Where did you stop hearing any sound?

Mine was around 13,000 Hz.

The speakers on my monitor did not give fair representation of the test signal. In fact, nothing was audible until around 250hz. I have no way of knowing whether any failure to hear above 12khz is my fault or the monitor's fault. Given the size of the speakers and absence of any bass, I suspect the latter.

Not a wholesale criticism, but hearing is not to be assessed in an all or none fashion; e.g., you can hear 14.75khz but can't hear 15khz. Rather, the measure is relative sensitivity. That is how many db down from some standard reference point the sensitivity to frequency X is, or conversely how much its amplitude has to be increased in order to be heard as same loudness as some other frequency. That one can still "hear" 12khz is separate from it being 14db less detectable than some lower frequency. I think it also fair to say that detection of a tone has to always be balanced against background noise. Sometimes, the perceived intensity of a tone will fall below the noise floor. That's why it is more useful to measure relative sensitivity. A person could still show evidence of sensing the tone bt it gets lost amidst all the backgroud noise so it doesn't feel like you're hearing it.

This is useless right now. Too many people yakety yakin to each other. I will attempt this in the privacy of my home! I am wearing Bose earbuds but keep on hearing about some stupid woman's affair she's having and she has a retarded thunderous laugh. You wouldn't believe what my ears are privy to right now.

And.....to think this is reality. This is porn in the making.

Thanks @Steadfastly , that was really cool. I did it with Bose noise canceling headphones on and I was amazed to hear something at 20hz. It was a low rumble like a train driving through the house.
My hearing was done by about 9200 however. No 20hz to 20,000hz for me.

Edit: I tried it a second time with Monster DNA head phones on, and they also had excellent frequency response at 20hz.

Edit2: My monitor speakers with 12" sub did nothing what so ever below 35hz B#(*

Using TV speakers:

90 Hz on the low end with the sound of the Whitemud in the background (I have my windows open because it is too hot in Edmonton in December.)
120 Hz is the apparent eigenvalue of my TV set up.
11.5 kHz and after that I wasn't sure my TV was accurately recreating the frequencies it was playing.

I used my Sennheiser HD380 headphones and could hear it all the way to 20k. But at some frequencies it felt like my left ear was better than my right. I also have a cold that is messing with my ears, so that might affect it.

This was interesting, @Steadfastly, thanks for sharing.
That's quite good. The high frequencies drop off as we age. I take it you are in the youngish bracket?

I’m 44, but sometimes I like to act like I’m 24 (although my body protests such behaviour). I was surprised that I could hear something for the entire range, as I have spent a lot of time in loud nightclubs and theatres.

I lost my left ear just past 8,000 and the right at 8,500. I knew this already from hearing tests while being diagnosed with nerve damage to my inner ear. I was told then I should have hearing aids. I’ve resisted, mostly because the good ones are beyond my price range.

Most of us are 24 or younger. Me, I'm 39 with 24 years of experience.

I think that is still good for a 44 year old. Most people have some drop off by that time. May your ears and your heart continue to be 24.

Kerry, it's astronomical what those things cost. My sister needs a new BAHA type and they are 6-7 grand.
