Even with PTA >25 some will pass APD testing. That does not mean perfect scores.
Sure, and of course. I was just answering the question about what “typically hearing” means in this context. Whether you think that definition is a good representation is a whole other debate…
But in short, they’d define what normal is (based on some variation of what was discussed), to try and exclude as the cause, then do tests on that “normal” population to establish a reference. Then they compare test subjects to that.
Not saying that process is perfect by any means, and interpretation of results really depends on the practitioners skill and experience.
