I can’t find what I was looking for so I’ll concede the point for the time being. Although the only references I could find re “sound” was radio emissions.
However, 2 things keep me looking. 1. One of the articles stated that the rings are composed of 98% ice particles ranging in size from sand to a mountain. That cannot help but make NOISE as these objects rattle and bang and scrape against one another.
2. The other is the statement that although the outer edge of the rings extends thousands of kilometers out into space, the inner edge is only a few meters from the discernable “surface” of the gas giant.
Therefore I maintain that if one could physically position himself anywhere near the planet, above or below the plane of the rings, they’d better be wearing shooters’ ear protection, because those rings are making a heck of a racket!
It has been a pleasure, Sir.
You have to understand what ‘sound’ is- it is pressure waves at different frequencies.
If you were in space and banged two rocks together you would not hear a thing, because there is no atmoshpere to convey the pressure waves.
