Well, using a GPS-based system, WLLH has, it is claimed, completely
eliminated sub-audio harmonics. And the technique was not
prohibitively expensive. I can't understand how this technque could
possibly have eliminated standing waves, however. But I can understand
that it might be possible to position the standing wave minima so that
they are located in areas of minimum population.
