Funnily enough, Yorick, I understand what you mean about sound and the effect of experience, because I had the same thing with colour when I used to paint, years ago. I stopped seeing colours the way we 'normally' do. Instead, I was seeing finely graded tints and shades, shapes, lights, shadows, and knew precisely how to get those colours with the paints to hand. I stopped saying/seeing, 'red', 'yellow', 'blue', 'brown' and started seeing/saying 'cobalt blue', 'alizarin crimson', 'sepia', etc. Same thing as you with sound, but different medium.
I just remembered! Must take up painting again...
