An interesting point about potential overlap of audiology and music/audio engineering.  I've no idea at all how much information and experience is shared in developing digital aids.

I'm far more seeing the privatised aspect of the field of audiology creeping in, with adverts all over the waiting room, and all reading material aimed at buying aids and accessories.  I'd assume that technology development takes place within these companies in a fairly closed way.

I'd love to see one of those fake heads!
