I never really focused on dB with pagients: I'd discuss their hearing loss in terms of mild/moderate/severe/profound, usually with the audiogram in front of them. People don't always register the numbers, and they're not always good at trying to interpret graphs. Whereas "My hearing loss is mild in the low pitches, moderate in the highs" is pretty easy.
Of course, then you have the engineers. They want the dB. And the software for programming hearing aids.
