An example of the Situational Hearing Aid Response Profile (SHARP) screen. In each panel, the listener's audiogram is shown in the open circles. The range of speech levels for a particular situation–in this case, a teacher's voice at 2 meters–is shown by the dotted lines. The shaded area shows the portion of the speech spectrum that is above threshold.
