I'm deafblind and started learning tactile sign (PSE, SEE and ASL) 10 years ago when I was diagnosed with severe-profound hearing loss. I can also communicate by using a raised print/Braille alphabet card, print on palm (POP), TeleBraille, Tellatouch, fingerbraille and realtime captioning with Braille output.
I can voice for myself and only use tactile sign for receptive communication or when communicating with my D/deaf or deafblind friends. When using a tactile interpeter, I prefer to use PSE or SEE.
ecp: I can relate to your frustration about wishing that you could communicate easier in noisy environments! When I attended training at my local deafblind center I was encouraged to learn sign. Since I had some aided residual hearing at the time, I didn't think I needed to learn it because I could still use an FM system. I quickly found out the hard way how difficult it was to communicate without my FM system. Being totally blind, I couldn't see to read lips or use other visual clues to help me understand what others were saying. Needless to say, this put me in some very difficult and embarassing predicaments.
I can't count how many times my knowledge of sign (and other alternative communication techniques) literally saved the day when I couldn't hear. Now I can go into any environment without having to worry about how I will communicate with others. In my opinion, the more "tools of communication" you have in your toolbox, the better.
Having said that, I realize resources are limited in some areas. At some point I hope you'll find more people who know sign. Are there any deaf clubs in your area? That might be one place to look.
