This is a cool hearing test link, and an interesting approach to adjusting your EQ.
One thing you probably already know: Human hearing isn't flat in its frequency response. In other words, most people hear certain frequencies better than other frequencies. So if you're adjusting EQ based on your test results, it might make the most sense to use the "Loss dB" column in the printer output as your dBs. Worth a shot if you like the way it sounds.
When you take that hearing test, there are those little grey dots on the graph. Maybe your resident audio expert can weigh in, but I think those are supposed to be the curve of general human hearing (equal loudness curves) Equal Loudness Wiki
. All that means is you'd want to adjust for the difference in dB between the grey dots and your results, not to match the curve itself. (The loss dB column = the difference between the gray baseline and your results for each ear.)
What's interesting about this approach to EQ is it might adjust for your hearing loss, but the way you hear stuff in the world from day to day is still probably better represented by a totally flat Equalizer setting. (Assuming that studio engineers recording the original CDs tried to make it sound like real life in the first place. Sometimes they try and improve on real life, kind of like cranking your TV color way up instead of making it look like real life.)
Equipment also comes into heavy play for audio flatness. I'm always floored by seeing audio gadgetry (Ipod, Aiwa stereos, BBE), with settings for "Rock" or "Pop," "Dance," etc. Are these supposed to emphasize something that's "missing?" My take: set flat and forget. Or adjust moderately to taste with your favorite music and leave. Different recordings will be different, so unless you like fiddling with EQ all the time, you might find a set and forget approach easiest.
If you're feeling ambitious and fancy, you can always try test tones (Stereophile makes a good test CD) and a dB meter. One time, I even used a laptop with a spectrum analyzer and test tones (for the subwoofer in the car). But the approach that makes me happiest is not to get too hung up, and enjoy the music. As Bill C. Says: "I experimented with EQ a time or two, and I didn't like it, and er, didn't inhale" Remember that the very best playback equipment includes no EQ settings. Currently all my equipment's set as flat as it goes.
