I have not spent too much time in conversation with any deaf, a little deaf, or alot of deaf or somewhere in between. My father is hearing but a virus killed hearing overnight years ago in one ear. I still consider him hearing. However life such as it is he may have to adapt fast if he loses hearing in the other ear.
I usually keep a up to date audiogram on paper. Maryland Hearing Aid Service who I did business all my life from the early 70's until the owner retired in the 90's or so usually provided me a copy of my gram partly for trucking purposes with, without hearing aid and word comprehension etc. That way I can accurately show the Medical Doctor in the Trucking Company I hire on with where I am in hearing. I consider myself deaf however I work equally well in both the hearing world and the deaf world. Some of my hearing in frequencys below 500 at 40 db or better is equal to or better than a hearing person at my age group. The lower the Bass, the better I hear it. (Or feel it rather)
One amusing thought. If a deaf tried to communicate with me they will discover that signed english is my basic language with ASL built on top with updated regional signs and words where I can pick them up. Being here in the south with Deaf is a little bit different than being in Maryland in some signs etc. Makes for a fun few minutes until one or the other learns and syncs the converstation to new words and signs.
