Interesting, but I would imagine this depends a lot on the quality of the headphones you use. Hmm, now I have a way to test headphone response. 
I got the following readings with various cans on the last 2 frequencies:
DT880s: 12KHz is -24db and 16KHz is -6db
HD650s: 12KHz is -12db and 16KHz is -6db
K701s: 12KHz is -18db and 16KHz is -6db
What does that mean? It means my hearing sucks above 8KHz.

I was surprised by how much of the higher freq. I could hear. I never tried to test my hearing before. Thanks for the link.

How high were you able to clearly hear?

30 Hz @ -30 dB
16 kHz @ -33 dB
This was using my Marshmellows with my girlfriend doing laundry. I'll try again with my MS-1s tommorow night....
The trick is knowing the difference between a tone and my PC's hiss 
What's a good score? 
edit : my laundry doin' girlfriend got
30 Hz @ -36 dB
16 kHz @ -39 dB
!

30hz: -48dB
12khz: -48dB
16khz: -12dB
Elsewhere I do well up to between 14 and 15 kHz then it goes straight up to the -12dB at 16kHz. It indicates to me that above 15 kHz I have a fair amount of hearing loss. But for someone 56 years old that may not be that bad. I used the instruction rigidly. These are my sound levels where those tones are just beginning to be heard at each frequency. The last time and my best time that I did this was when I used my ATH-ANC7 noise cancellation headphones. This curve compared with previous tests was much smoother across the audio range much like the typical sound profiles you see on the threshold of audibility curves. Only for the audibility curves the scale is inversed on the vertical side.
Be careful that you don't increase the levels to high just to get a reading.

i'm really not sure how to use this, but it's fun making little songs out of the noises.

interesting
with the HD650 my threshold at 30hz -40 .....and 16khz -54 (what veil!!!???)
with the MDR 7506 30hz -42 .... and 16khz -46
my test environment was a bit traffic noisy and 7506 are closed.
so on this test through my laptop, the hd650 has more top end and maybe less bottom end than the sony! wtph!
so, a really inefficient pair of cans would be telling us we are deaf on this threshold test, straight out of my laptop?

At what volume are you supposed to do this test at, anyway? Won't it be different for everyone, making the dB levels totally useless?

My take on this is to use whatever normal volume you want at the initial frequency of 1 kHz. Don't go higher than your normal volume. You will defeat the purpose of the test.
