In a blind test, audiophiles couldn't tell the difference between audio signals sent through copper wire, a banana, or wet mud — 'The mud should sound perfectly awful, but it doesn't,' notes the experiment creator

Who knew listening to a banana sounded so good?

    5.4 Electrical Conductivity Measurement This method includes electrical impedance spectroscopy (EIS) and dielectric analysis (DEA). The physical state of a material is measured as a function of frequency in EIS and the frequency ranges from 100 Hz - 10 MHz. It is simple and easier technique used to estimate the physiological status of various biological tissues49-52. Experimental frequency response of impedance is characterised by electrical equivalent circuits of materials. The physical properties of materials can be quantified by monitoring the changes in parameters at the equivalent circuit, among various equivalent models proposed53-54. DEA measurement is used in high frequency areas, generally 100 MHz - 10 GHz. DEA is used in moisture estimation and bulk density determination

    So a overripe banana is an interesting high-pass filter, kinda like a capacitor, though the big takeaway is the conductance vs ripeness.

    So if you want to test if a banana is ready to eat, hook it up… preferably with several other bananas in series. If the music is too loud, they are ready. Too quiet, and it’s not time yet.

      I only listen to music with overripe bananas. It sounds best that way. Copper wire just doesn’t sound as good. Believe me: My ears are very sensitive and superior to yours.

        You get much better conductivity with plaintains because the cross-sectional area is bigger.

        But because my ears are so discerning, I only put my audio jacks in jackfruit.
