Mystery solved, mystery created - Auroras do make sounds

Sound and light show

The claim that sounds accompanied the aurora borealis was long dismissed as folklore.  But now we know.  Microphones set up in an area of frequent auroral activity recorded a variety of "clapping" sounds along with pops and bangs and "sputtering."
How are sounds produced by the energetic particles creating the Northern Lights? Ah, that's the NEW mystery.
