Can you be absolutely sure about that? 
Funny this should come up now - I'm off to the local hospital audiology department tomorrow for a "reassessment" of my hearing. The digital aids I've had for about four years now have, apparently, been superseded by models that can be adjusted for 12 frequency bands, against my present models' four.
These have been great (Oticon - same brand as Dick's IIRC); they replaced very basic analogue models. My right ear is far worse than the left (had surgery on the right one 20 years ago, so it would have been even worse by now). Doubt, however, that my NHS ones will be as super as Bob's 
However, while he can choose which hearing aids he likes, I could still buy those two iMacs..... 
My twopenn'orth: I think Bob got it right putting this in Tech
And then, I'll be (even) more responsive re my wife's dulcet tones...
My late Uncle Bernie was hard of hearing and therefore wore a hearing aid. Whenever his wife started to annoy him, he would conspicuously turn down the volume. Needless to say, she was annoyed in turn.
