The noise referred to in the title is sometimes referred to as space noise. Not referring to radio static at around 60HZ. As the earth spins and rotates, a constant sound is generated and is detected with underwater sound surveillance equipment. This sound is 6-8HZ. Is it possible to boost the strength of this signal and run it through attenuator banks? Maybe, enough OHM's could be accomplished to provide 12 Volts of useable current.
