For that money, she could get stem cells and possibly improve both ears. This will give her better hearing with and without HAs and she may even find she no longer needs HAs! I have a blog on stem cells and am going that route soon.
With your 60db loss, you would not understand any speech without your HAs. You need at least 40db gain across to place your aided thresholds at the 20db level which means being at the top of the speech banana. It sounds(pun intended) like you are being underamplified and thus, normal speech is too quiet. I was able to understand more speech when I got new HAs which made everything louder. I really wish I had only a 60db loss, my speech remains poor but at least I’m great at lipreading.
