Excerpt: What? You say you don't believe in prescriptive methods for programming hearing aids? Really? Then let me ask you this: Your Monday morning patient has a relatively flat 60 dB loss of cochlear origin. Would you program his hearing aids with 60 dB gain? Of course not. How about 10 dB gain? Not good either, right? Guess what—the moment you reached these conclusions, you're already using a prescriptive fitting approach.
