Eli5: How does using technology to hear sounds from mushrooms work?

Question

Or is it all nonsense? I’m assuming they use effects to change pitch and make them into melodies.

Answer 1

Those things where they put clips on plants/fungi and “listen to them” is basically a speaker that outputs sound based on changes of capacitance and resistance between the clips. It isn’t really the sound created by the plant/fungi, but instead sound created by the normal living processes causing those electromagnetic changes.
