ATS...? American Thoracic Society? Australasian Tunnelling Society? Advanced Telescope Society? Or maybe Association of Theological Schools?

Neither Google nor Smithsonian searches turned up anything on it. I know they've made sound of the Sun but I don't think the method used there can be used for a planet - it involved fine measurements of the sun surface which, like the surface of a bell if you could see it close enough, vibrates to the acoustic waves propagating inside.

Planets, either solid or gaseous, would not have that effect. In both instances I think the atmosphere would absorb any potential ripples that could be detected from space.

Then you have the whole issue of how they'd know there's a note missing? What scale are they using?

I'd think any planet (unless dead) would have awhole range of acoustic effects going on - how would they pick out the basic tone so they could know whether or not it fit into whichever scale they picked?

My guess? Bogus claim
