Answer:
http://spaceweather.com/glossary/inspire.html – Sferics, tweeks and whistlers and other “sounds” picked up by VLF receivers. Essentially, the sound of mother nature herself in the radio spectrum!
Whistlers?
Auroral Sounds

This has more to do with light than with lightning. So not sure of the answer!
sferics tweeks and whistlers
ICE!!!!
these sounds are made by the ice surface!!
change of answer, it isn’t ice, rather the sound heard before lightning strikes
VLF radio generated by lightning.
also known as whistler.

Sferics, tweeks and whistlers… Oh My!
Electrophonic sounds – sounds produced by direct conversion of electromagnetic radiation into audible sound, in clear contradiction to the physical laws of normal sound propagation.
Noise Prior to Lightning Strike? (The clue is obviously a reference to “lull before the storm”)
