I saw something a few years ago explaining this. They think now that the worms are not drawn to the humm, but rather fleeing from what sounds like a predator, a vole or something.

When I was a kid, the big thing was using a war surplus hand-cranked signal generator (used by the signal corps to power their field equipment; it didn't create signals). Push wires into the ground a couple of feet apart, crank, worms come to the surface.

Back in the late 70's, we would take a piece of 3/8 rebar about 18" long, pound it into the ground at least 6", attach the wires from the cut off socket end of an extension cord, and plug in the cord. We used one of the cheap 6' cords and plugged it into a longer cord. We did not stand in the area while the cord was plugged in. The ground was usually a lawn. The worms came leaping out.
