After a short look at Rx for high frequency hearing loss, it seems that the best solution with current tech is cochlear implants.  Selective amplification of high frequencies doesn't seem to overcome the problem of damage to the high frequency hair cells in the cochlea.

Unlike hearing aids, the cochlear implant procedure causes irepairable damage to the cochlea which is compensated by the implant, but ultimately not reversable.

The fidelty through such a device is far worse than what most hearing deficent people have and is currently used only with select patients.

In Canada it can cost upwards of $75,000 and can take more than a year from your initial interview.

It would be interesting to do an experiment with a good headphone amp and phones combination together with a 1/3 octave equalizer to see if whether with adequate electronics you can actually flatten the apparent response.

I don't have an equalizer anymore, unfortunately, so I can't try it.  But maybe someone out there who is hearing-impaired could do the experiment and report back?  A good starting point would be the graph from your hearing test; invert it for the equalizer.

I've done a bit of reading on this subject since I got hearing aids, and apparently the problem with most current hearing aid designs is they do not really pay much attention to frequencies outside the speech range, and also the dynamic range of the ADC in the aids is not large, so they clip badly trying to boost the frequencies we have lost that are musically important, both bass and treble.

if i were in your shoes, i would be lurking on ebay right now, looking to snipe a quality pro-audio 2 channel 31 band eq.  and, i see no reason why it could not be used for loudspeakers, as well as headphones...
