I don't know of any such studies, although Bakker's illustration on page
145 of THD at least depicts the path the air might take in two sauropod
genera. _Diplodocus_ has a sealed off chamber which could conceivably be
studied in detail, whereas _Brachiosaurus_ is presumed to have had a fleshy
chamber (which is not "roofed over") which could amplify and control the
sounds. _Brachiosaurus_ basically has big spaces topped by a bony strut,
so without soft tissue preservation there isn't much to go on here.
Perhaps the camarasaurs inflated elastic nasal flesh in much the same
manner as a proboscis monkey's proboscis or an elephant seal's nose (one
hesitates to say trunk)! This same idea has been proposed for the
ornithopod, _Saurolophus_. Bakker suggests that _Diplodocus_ would produce
a "brassier" sound than _Brachiosaurus_, due to the surrounding bone.
