The voltage from HIFI-equipment is very low, and bodily resistance is extremely high, so you couldn't "zap" yourself for the life of it. Probably the voltage is too low to work for our purposes, but then the voltage of the headphone-outlet can be varied to some extent.

We need to know the exact voltage used in the experiment ...
