Equalizer for hearing loss

I created a thread ' high quality equalizer' but think this title more appropriate as I'm dealing with hearing loss and hoping others may benefit from the discussion :)  I just had ear exam and am down 20 to 30 db in left and right ears to 4000cps. Down 90 db at 6000cps (or hz) , and 80 db at 8000. Trying a basic hearing aid now and thrilled with newfound music listening pleasure ! I also have tinnitus that's too loud to measure-as a result of a head injury from a car accident in 1989. I'll post more later.
Had my hearing test last week. Up to about 4000 hz left is down about 30 db and right about 20-25db. Then graph falls sharply to -90db at 6000hz then up to -80 at 8000 for both. I noticed the hearing test is only at 250, 500, 1000,2000,4000, 6000 and 8000. I'm presently trying a very basic set of aids and finding an exciting improvement in my loudspeakers! Depth, width and detail in sound all vastly improved :)
So far so good, for this much older "old-timer." Only the age-related reduction of high frequencies as a resident in the suburbs. I've read that such loss does not happen for those living far from such civilization noise, or at least not as much.

I took a SPL meter outside to see what the background noise level is. I read around 49 dB, C-weighted. If I go out to the remote areas, it's really quiet there, without any wind (didn't have the SPL meter with me then - next time).
I purchased widex moment hearing aids. I am now able to hear upper frequencies I was missing. It was like I upgraded my speakers. They were not inexpensive but with the prices of HiFi equipment today I was ok with the purchase.
