It would be a promising development to see the "multitone test signal" make available for replication purposes; actual measurements would appear to be trivial.
One interesting aspect of the graphs in Part 5, i.e. Figures 6.7 and 6.8 is that the right-hand plots, those taken at the load, would appear (at least by superfical appearance) to represent a net sum increase in energy compared to the plots taken at the source; I'm assuming the y-axis (SPL-db), can be construed as a measure of energy.
Assuming this is the case (difference plots would help) my only guess for the apparent paradox would be that the additional enegry is Back EMF that is attenuated by the cable (to account for the lesser energy at the source).
