For decades, powerful microphones have already been sent with the voice coil mounted on the principal of the microphone's transformer, and maybe not called to surface (‘floating'). The microphone's case is normally linked to the cable guard, that is connected to the mike amplifier's soil (see Rane's site for more discussion).
By and large, energetic microphones are very quiet devices consequently of the mixture of transformer solitude and balanced, suspended transmission lines through the duration of, along with shielded, humbucking coils.
Therefore you will want to guitars? Instruments are once affected by noise. Humbucking pickups are just an incomplete (though important!) solution. Well-known option would be to float practicing the guitar pickup to a healthy production, being a microphone. The same strategy was published this 2001 patent request like this Prisons In Pennsylvania?
