There is a very slight drop off (about 10 Db) between the bad ear and the good ear at 2,000 and 3,000 Hz. It is only at 4,000 Hz that the real
problems start -- a big 55 Db drop, followed by 60 Db at 8,000.
I have no conversational disability. As I mentioned in a previous thread, I got a 100% in "Speech Audiometry" in both ears. When I experiment on myself, however, I do note some issues.
