I sympathize with the auditory hallucination issue...
However...
I can safely say, you're gonna have a helluva ride finding decent hearing aids, especially if you hear quite alright, Unless u manage to get medical clearance {your psychologist/psychiatrist, for example, could recommend or prescribe a low dB hearing aid, inner ear type}
I'm profoundly Deaf, and I have a really...fucked up dandy time getting medical/insurance approval for 1, every 4 years

[ they happily talk about cochlear implant, but that's a different issue, different thread ]
I do wish you good luck, if they say that'll help you.
