The lines have the same configuration as in figure 7.2 except in the treble region the order is reversed. The green line now has the same value as the purple line did in figure 7.2 and the purple line has the same value as the green line did before. Same goes for the blue and light blue lines.

Starting from the low end the lines all come together at just above 300 Hz. Starting at 100 kHz and moving down in frequency all 5 lines come together at about 1200 Hz. They do not separate as they did in the previous figure but remain as a single line. See the text for a discussion of this phenomenon. End verbal description.
