VERY GOOD.....I've been looking for a hearing test like this for awhile. Thank You!! This is nice that it even holds your maximum so you can get the results after you finish. Very Nice!!

Here is what I got using MY headphones. I could actually hear down to -91 at the 16kHz range, but that area of the sound spectrum (upper and lower DB range) sounds like a low "wind" noise to me (like white noise) "static" with the higher frequencies removed. So I don't even consider that area anyway
I do have a ceiling fan running overhead. I will try again this evening to see what difference it makes to shut it off...and a full day of listening

Unfortunately there is a constant procession of cars travelling past my window, which makes this a bit more challenging but i've spent about twenty minutes testing myself using headphones on a laptop.
The first couple of tests seem to return uniform results across the board at -90db.
That only illustrates to me the extent to which i can hear the generated 'clip' rather than the individual characteristic of each pitch sample.
So i tested myself to see at what minimum db i can practically discern the pitch of each frequency. This is my result:

Very good scores. I had the same challenge with the "clip" sound when file was activated...I only used the scale that showed the actual "tone" when it was available. Nice online hearing test available though What headphones did you use? I used a very cheap pair of Numark HF125's that I like for EVP work. Good volume down in the static area (needed), and comfortable for hours of use.

Hi clockdryve :-)
Yes, i related to your previous post regarding the ability to detect a generated clip but not hearing it fully as such. My headphones are cheap JVC $10 type ones, that fit inside the ear (like ipod h/phones).
I did notice with the test also, that it was easier for me to work downwards (say from about half-way so as not to blast me ears!), than to work up from the very bottom.
It gives hearing something to adjust torather than beginning from complete silence.
When i was usin the test i was imagining whether i could detect these very quiet signals if i was listening on a radio frequency. That's what prompted me to see what practical levels of each frequency i could definately make out.

This test only proved one thing. I am old. And yep, as expected, my sensitivity to sounds above a certain frequency is like....nil? Perfectly average for the 40 and up crowd. :D
Testing consisted of the following rig:
Dell L702X laptop.
USB -> Headphone amplifier "dongle" -> Sony NC60 cans.
Swapped the cans for Beats Audio in ear buds, retested.
Swapped ear buds for HP brand communication headset, over the ear open style.
Swapped them all out and just listened to the built in 2.1 speakers in laptop - then again over open air shelf speakers.
My hearing cuts off at the same damn frequency every time! >.< Grrrrrr. I'll be deaf as a post come age 60 onward.
I need to borrow me a 9 year old kid from someone and have them check and make sure it's not equipment malfunction. :P

That's an interesting link. Thank you. It provides a rough reference for hearing, but of course doesn't take into account the frequency response of your headphones or sound card.
The sound card for all intense and purposes for this test will be relatively flat, but headphones vary significantly, so a meaningful test will be calibrated against the headphones that will be used.
On a calibrated test I can detect -18dBm at 17.5 kHz, but on this one, with my own headphones (Sennheiser HD400) even 16 kHz inaudible below "0dB" whatever that actually is as it also depends how you have the volume set!
Anyway, useful for comparison.
You young 'uns out there should be able to hear 16 kHz down to at least -24 dB on this scale. (No cheating by turning the volume up!)
