How good is your hearing ? And how do you know ?

@bdp24

Understood.

I've also used Musician’s Ear Plugs since the 90's.  (Along with heavier duty earplugs if necessary).  I'll still use them even in a pub/restaurant if it's really loud (and as I'm sort of a "foodie" who loves dining out, it's depressing that restaurants have been ever more deliberately designed to be louder and louder, so they feel like a "happening place.")

As for Tinnitus and sleeping, I decided long ago not to use masking, simply because I didn't like the idea of feeling reliant on some external help.  So I just got used to it and generally don't have an issue sleeping.
(Unless I've had some recent really loud noise exposure which makes the ringing worse for a while).

>>High end loss of course, almost nothing above 15k.<<

I was tested yesterday.
Current high end test limit is 8000Hz.

@gawdbless you can't "hear" 7hz, it's inaudible.

It is technically inaudible. Frequencies that low are felt, not heard..

Having begun to experience hearing loss and concomitant tinnitus in my 60s, I finally opted fir a set of (relatively) high-end Phonaks, which were computer-tuned to audio spectrum of greatest loss, round 4000 Hz, +/- 500 Hz.  Listening to a variety of music on a “mid-fi” rig there is a clear improvement in overall detail in the mid-frequencies, with little difference noted in the two extremes.  Now, with hearing compromised, it doesn’t seem worthwhile to go all-in spendy for system upgrades, as the gain in detailed nuances would probably be washed out, or somewhat distorted by the hearing appliances.  However, I would be interested in hearing from audiophiles who indeed have compromised hearing, use aids, and can ascertain sonic differences between various pieces of hi-fi kit as one moves up the quality ladder.
