I can say that when we bought our CAN-8 lab a few years ago at Ashland University, it was made clear to us by the vendor and the manufacturer that the ups and downs in the graphic represent volume and nothing else. The graphic helps you see pauses=E2=80=93end of phrase, word or sentence (since pauses are silences). The line across the top indicates the ceiling where you will get clipping if your source is too loud. Instructors tell students this in orientations and try to teach them to read the graphic for those purposes. I usually play back a nasty clipped file as a demo of what "this" visually will sound like. It's true that, unless told otherwise, some students do think that they should try to match the graph. That's one reason we make a point of telling them not to. =20 =20 =20 Mary Ball Ph.D. Student Foreign/Second Language Education Ohio State University
