The chosen propagation media (wire substitute) wouldn't have significant frequency responses differences for those lengths for that level of power in the audio frequency range.
You'd need to have transmission-line effects kick-in which would occur at higher frequencies and/or if a cross-section of the signal propagation paths would have a significant difference in impedance. All three of the chosen medium act like simple power-sink resistors in this scenario--attenuating the signal consistently across the power frequency spectra.
Seriously, just do a frequency sweep and plot the log of the output responses! But no, that would be far too straightforward an experiment.
What really matters is the signal source, any amplified distortion in the signal, final sonic transducer (speaker), transmission medium (air density), transducer orientation (for higher frequencies), and the individual listener's ear.

"However, the tester surmised that introducing the materials into the circuit is just like adding a resistor in series, and they’re unlikely to distort the audio too much, except by lowering the signal level."
It's really a terrible write-up (AI?), pure click bait.
The final sentence is just garbage:
"They then tried various materials like mud and banana, which, although they’re pretty poor conductors, still seemed to introduce imperceptible changes to the signal, at least for the average person."
What does that even mean? It's trash.
