I think I am getting these "growing pains". I still am not 100% sure what the transpositional sounds are really supposed to sound like....any way to describe it? Not sure what sounds will make the area of the sound transposition.
The more they have to transpose, the stranger it can sound. It's hard for me with normal hearing to tell you what it should sound like with a given hearing loss. I will say this though, the feedback from a transpositional aid sounds like crickets as opposed to a whistle.
