I lost 75% in my left ear when I was younger due to an ear infection. I have no problem with the high frequencies in that ear, its the low ones I cant hear. I know a little signing, not much, mainly the alphabet. I've always wanted to learn though and I've thought about taking classes. I read lips pretty well....
I'm also (not legally) but blind
Im a -7.50 in both eyes so If I dont have my glasses on its hard for me to hear and I cant hear well if you're walking in front of me and talking. I think with my right ear taking up the slack, thats the reason I have a very low tolerance for a lot of bass in anything. It throws my equilibrium off something terrible.
