The last frequencies to usually go are the lower root frequencies but of course not always.
With whatever residual hearing you have left you do have to relearn how to hear. Especially with no aids. Take mine away and I could probably hear 120 Hz and below if the db level was at least at 80.
Hearing aids give you nothing below 120 - they are primarily for speech. Beats even with hearing aids are hard to hear.
Beethoven was a wonder, but I'm guessing he had some residual hearing but was deaf to conversation. Remember orchestras can peak at 110 db can't they. And if you have some root level hearing you can hear the vibes by placing your ear against the piano. I'll have to look more into how he did.

Appreciate the thoughts here Mac -

I'm not for giving up - I started the thread looking for software and/or technical advancements so I can keep doing what I love.
Right now I some info on the use pitch correctors with PG Products.
