Phew! You are a bright young woman- despite being hearing-impaired you write clearly and well. My first devices were analog and I hated them for all the same reasons you dislike yours. You can't pick individual voices out of the background noise to make sense of conversation. The aids are useful one-on-one in a quiet place and that is about it. I'm shocked your audiologist has not explained this clearly to your mother. The problems are technical, not emotional, and it was a very smart move to come on this forum and ask advice. Do you have any classes at school that would let you study the technical reasons hearing aids sometimes don't help?
(I think the system your teachers use is the hearing loop (http://www.hearingloop.org/)).
Your autoimmune disease puts a spin on your situation that complicates things for everyone. I imagine your mom has been deeply worried for you a long time and that the burden of health care costs on your family makes all of you quite nervous about expenses. Your move toward taking charge of this entire issue is going to be a big win for the whole family.
Finally, cuz sometimes I talk too much, check this thread about migraines and hearing;
Don't let is scare you since the 2 are linked for only some people, but do tell your autoimmune doc you think the devices bring on migraines sometimes. See what s/he says. I am not prone to migraines but sometimes I get headaches because the ear molds irritate me.
THIS IS A JOB FOR SCIENCE! oh wait, I said that already...
I have Ménière’s disease which for me causes distorted hearing. Pure amplification doesn’t help. The best descriptor I’ve found are “everyone sounds like Charlie Browns teacher” or “it’s like trying to listen to someone three doors down”. Yeah the amplification level may be kinda ok but it’s garbage. I now have a cochlear implant in one ear and it’s better than a hearing aid but not by much. Truth is I may have waited too long to get it. Nonetheless it seems to get better over time.So I'm 15, 10th grade, I've had hearing aids since 3rd grade. I have a nasty habit of losing a hearing aid every now and then. In the past 6 years I've lost 2 hearing aids, and Monday made 3 hearing aids. When I told my teacher the other day he asked me why I don't just have a cochlear, and I got a little mad, because of how much I don't want one. When I told my mom she was pretty calm about it at first, but understandably on edge because it's not like money to replace said hearing aid grows on trees. But last night we got in a fight because it's not acceptable how often I lose them. There are a few things I have that cost a lot less money that I have never lost such as my pooh bear I got for my first Christmas, my laptop and then I wear 2 necklaces, 1 choker I made from safety pins, jump rings and a pentagram for Supernatural and a gunmetal chain with a piece of carved onyx. The necklaces are my safety blankets. I rub them when I'm stressed instead of drawing butterflies on my arms or snapping a rubber band on my wrist. Because I have never lost these things but I've lost my hearing aids, my mother is in a word, pissed. How do I explain that I don't like my hearing aids, and I don't care about them without getting in even more trouble? Because I know I'm not the only person that hates wearing hearing aids and they don't help me, they only make things worse, but for some reason my mom can't understand that. How do I tell her without it ending with her having a meltdown? Please help any advice or personal experiences are appreciated.
