Here is Nolan's aided audiogram from John Tracy, transposed onto an audiogram with a speech banana. We sort of wondered where /f/ went- I suppose it disappeared because he can't hear it. The magic box shows that the aids aren't meeting DSL targets, either.
Here is his unaided audiogram, with bone conduction scores. Currently, his right ear is testing better than his left. The shaded yellow area represents the air-bone gap, indicating a conductive component to his loss. The frequencies above 2000Hz do not show an air-bone gap, indicating the loss in that region is purely sensorineural.
