Here's an example of northern lights associated sounds...

"Our research proved that, during the occurrence of the northern lights, people can hear natural auroral sounds related to what they see. In the past, researchers thought that the aurora borealis was too far away for people to hear the sounds it made. This is true. However, our research proves that the source of the sounds that are associated with the aurora borealis we see is likely caused by the same energetic particles from the sun that create the northern lights far away in the sky. These particles or the geomagnetic disturbance produced by them seem to create sound much closer to the ground," said Professor Unto K. Laine from Aalto University.
Details about how the auroral sounds are created are still a mystery. The sounds do not occur regularly when the northern lights are seen. The recorded, unamplified sounds can be similar to crackles or muffled bangs which last for only a short period of time. Other people who have heard the auroral sounds have described them as distant noise and sputter. Because of these different descriptions, researchers suspect that there are several mechanisms behind the formation of these auroral sounds. These sounds are so soft that one has to listen very carefully to hear them and to distinguish them from the ambient noise.

The theory one hears about most often about those sounds is that they are created by the same thing that creates meteorite sounds - intense bursts of radio waves that hit the ground and when their wavelength is just right they cause a reaction vibration in plants and minerals. Because it is radio white noise, covering the whole spectrum, every burst of it is likely to find something with the right wavelength to interact with.
I heard a lot of this during the last big leonid shower - a wonderful soft rattling hiss every time a big leonid flashed.
