That is a question that has been discussed for a long time.
Some people are convinced thet the aurora has a sound, while others say that it is impossible.
One thing that makes some scientists doubt it is that people who have heard the sound say that it happens at the same time as the aurora is fluttering the most. Since the sound is made of waves that move slower than the speed of light, the sound could not possibly be heard at the same time as the light is observed. The aurora is located approximately 100 kilometres from the Earth's surface and because of the long distance the sound would be delayed by almost five minutes compared to the light. Despite all these doubts, a lot of people around the auroral zone have heard sounds related to very strong auroras. These sounds have never been recorded, but the descriptions of the sound are very similar from all around the auroral zone.
