Here's an odd one...
These guys use contact transducers to record the sound of the metalwork of pylons (transmission towers). The resulting sounds are influenced by wind blowing through the metalwork, wildlife, rain and the power itself. Some quite unusual noises. you can actually hear the power harmonics. I wonder what the biggest contributor to the "dirtiness" of the electrical sound is. Just general switching and power controllers en-masse I guess.

It does make you think that maybe listening to power lines could be useful in diagnostics for things like ferro resonance. With an inductive loop and amplifier you could monitor the lines from the vicinity without any need for direct contact.
