Deep sounds of hell

What does Hell sound like?  BLDGBLOG wonders.

[David Toops] calls this, citing the Aeneid and Paradise Lost both, the "auditory configuration of Hell": "The auditory configuration of Hell is an opposition of low homogeneous moan and confused Babel, of deep tones and threnodic shrieks, as if combining the outer extremes of human perception is the most authentic expression of damnation." There is acoustic "distress," Toop writes, somewhere "between roaring water and the tumult of the wandering helpless unburied," where dogs howl and angels whirling to their doom are deafened by "the bellowing of the Earth itself." 

There's a ton of music doing this already, but I wanted to cite this as a nice evocation.
