I sympathise, though know nothing about the "culture".
I do view deafness as a disability, and I think it is ridiculous that "disability" has become a dirty word. A disability is just a thing that makes it difficult or impossible to do something the majority of the population is able to do. So you compensate for or replace that thing. Sign language, lip reading, cochlear implants, alert lights rather than sounds for things like phones and doorbells, all valid compensations or replacements. Disabled =/= invalid. >.<
I have had hearing issues all my life due to a relatively common structural defect among young children wherein the eustachian tubes are too close to horizontal resulting in extremely poor drainage from the middle ear and a condition referred to as "glue ear", causing frequent ear infections. Most children's eustachian tubes correct during childhood, but mine have improved but are still abnormal in their angle, meaning that I always have gluey, gummy ears. As an added bonus, my eardrums are heavily scarred from infections and three rounds of grommet (external drainage) tubes.
As a result, my hearing is extremely muddy, and I rely on a combination of listening and lip-reading. It's not something that would be aided by a hearing aid, as all testing shows my perception of volume is normal or better. It just means that there are some people who I have trouble understanding because of the way they talk -- I have one friend who is almost completely un-lip-readable, so I'm always asking her to repeat things, and I can't understand a word she says if there's any background noise -- and I had problems at school with teachers who could not understand that I couldn't understand them if they had their back to me. One particular b***h kept giving me detentions for asking my neighbour to repeat things to me, despite a letter from my mother explaining the situation. >.< Grr.
So, yeah. My story. In case you care. Probably not. ;p
