Mac, that's true.

However, Ian sent me his audiogram back several months ago, and he does also have some broad-band loss that the other bands will help to accommodate. I don't remember the shape of the audiogram very specifically. The problem with audiologist audiometry, however, is that the audiograms are done on an octave basis for the most part. There could be some notches at a more narrow resolution than octave band. Part of this is for efficacy of getting the audiogram done, as well as also somewhat a limitation on what the EQ/filtering is capable of in the hearing aid.

Most likely a single graphic EQ will do - those that I've used have generally 24 dB of range (+/-12 dB). Where he has no, or relatively flat loss, he can set those at -12 dB, and then go up from there as necessary, up to a 24 dB difference from where it's 'flat'. Then the big gain knob can make up for the 'flat' quite easily.
