This post came through on Facebook from The Musical Instrument Museum. I thought it would be of interest to the Nuts  "holographic interferometry" to visualize soundboard vibrations--and it's plenty interesting to us, so ... In Pictures: Stringed theory www.bbc.co.uk/news/science-environment-13573631Researchers reporting at the Acoustical Society of America meeting present images that show the tiny movements of stringed instrument soundboards.

Nice find IRW. Pictures are always nicer then your typical academic dissertation.
Not to drag this away from the "Beer Can Holders" section too far, but wouldn't it be interesting to try this on certain electric guitars?
For example, one of Jimi Hendrix's Strats versus one of Stevie Ray's Strats... Or Brian May's guitar... ...or Jaco's bass...
Or grab a product line, Strats or Les Pauls for example, through a few decades and document how or if they changed over time... Or monitor a new guitar for 20 years to see how the character of the wood changed over time...
Might settle the tonewood debate for good...
Man, I need to get out more...

Great link, irwired, really interesting.
Very useful for builders, but I think Cyn has a good point. After all, there's a lot to be said for basing your world view on science and rationale as opposed to witchcraft and the anthropomorphism of nature. Likewise, lets put all this money spinning mojo mumbo-jumbo up against a good bit of physics!

Very interesting link. I liked the comparison between the old powder method and the new holographic analysis - a nice continuity of science and craftmanship over centuries.
Another modern addition to such work is the ability to calculate such response patterns by analysing dynamic modes of vibration. We do it for building structural designs every day and theres no reason why the same software couldn't be applied to instruments, and no doubt has been.
