You could say a conductive copper wire used as an aerial is 'neutral', but it picks up electrical signals ie: 'noise', radio waves etc.Is the human body neutral? If yes then why does the speaker make noise, when its jack touch any human body?

The human body is just a bag of salty water, as you may know salty water is conductive, so your body acts like a receiving aerial picking any local EM radiation.
Touching an amplifier input just completes the circuit path to ground for the EM signals, which get amplified.
OK.?
E
No,Is that true??
