Russell,
I have to disagree with you. I will, however, start with a caveat. Not everyone's hearing loss is the same. Nevertheless, you can get very close to your previous hearing by using hearing aids.
First of all, modern digital hearing aids can fill in the gaps that your "normal" hearing has lost. That is their job. They are set electronically to do that. The loss of frequency that most people have is not an absolute loss. Amplifying those frequencies will, in the majority of cases, return your hearing to approaching normal. That is why my morning is peaceful until I put on my aid and get drowned out by the birds that have gone unheard up until then.
With the digital hearing aids that we get in the UK ( Free from our wonderful National Health Service), there are a number of pre-sets - normally three ( all around sound, face to face sound and loop - or 1, 2, or 3 beeps when you adjust them). There are other settings that are available. One of these, known as "setting 3" is specifically for music. The other pre-sets are set for speech with high db and high hz so that you can get the s and f sounds. They will not be giving you a broad sound range ( you may get clicks in higher registers). You can ask your audiologist to replace one of your existing pre-sets with the music pre-set.
I only heard of this from an audiologist a few weeks ago, so it's something that I have yet to try, but you can be sure I'll be asking for it at my next appointment. I do not need the loop setting.
Finally, Russell, if your hearing aids are old, they may be analogue, rather than digital. Digital will make a huge difference, as an audiologist can set them for your specific hearing loss. Do go back to your doctor and check this out, you will appreciate the difference.
