Okay, here is an interesting article about pottery recordings.
http://tenser.typepad.com/tenser_said_the_tensor/2006/02/pottery_recordi.html Be sure to read the comments below the article. One of the posters mentions "Time Shards" and where Benfield got the idea for the story.
Another find, there is in fact a minor discipline called Archaeoacoustics and some experimentation.
The Proceedings of the IEEE is a peer reviewed journal, but the article quoted a letter to the journal, so I don't think it got the same peer review that a regular article would have gotten.
Here is the University of Pennsylvania's take on the Woodbridge letter which essentially busts it as an April Fools hoax. It shows some interesting investigation into how they came to that conclusion.
http://itre.cis.upenn.edu/~myl/languagelog/archives/002875.htmlWhat little I can find on Woodbridge so far is that he did indeed graduate from Princeton and did some work on underwater ultraviolet lighting for divers. But this reference is more up our alley.
http://ssi.org/ssi-supermodels-part-2-make-your-own-ssi-mass-driver/ Imagine that. Woodbridge also wrote about Edgar Alan Poe and article titled “J.N. Reynolds: Father of American Exploration,” Princeton University Library, among others. I am guessing that he followed in his father's footsteps with an engineering degree, but that is only a guess. His dad appears to have been an engineer and his grandfather did research on Perrywinkles. His sister Margaretta, passed on in 2004. The obit mentioned that Woodbridge III predeceased her.
Okay, I just about ran that little research project dry.
