An aside – the Aurora. 

Talk with Andy Charalambous about the doppler effect, sonified vibrations and the aurora borealis.

Think like an architect: 340, Mr. Greig Paterson – Bartlett school of Environmet, Energy and Resources.

I spoke with Andy Charalambous about his desire to find out if the aurora borealis makes sound. Theoretically, it should do, but its ‘sounds’ have become entangled with the local mythology.

Although in 2002 a Finnish study claimed to have picked up there were natural auroral sounds, (clapping and hissing sounds) however Andy wasn’t convinced those sounds were actually coming from the aurora.

Could an atmospheric light show produce sound waves that propogate through the air to the ground? Theoretically, yes, However, perhaps the upper atmosphere is too thin to carry sound waves.

It reminds me of the oft-quoted thought experiment, ‘ The objects of sense exist only when they are perceived; the trees therefore are in the garden […] no longer than while there is somebody by to perceive them’
