i also like the idea of using aspects within a recording studio to describe different subjects to do with acoustics and sound; guitars, acoustic foam, microphones etc.

online guitar tuner with sound.

if you click on the strings of the guitar, it produces the correct pitched sound for the string so you can tune your guitar to it.

just thought id put this up to remind you guys that we could use this concept, possibly to help explain how sound travels within an acoustic guitar as a simple example? pherhaps we could produce an animation of how sound travels within an acoustic guitar also?

This has got some quite useful sciencey type info on acoustics of buildings on it, i know it's about classrooms but it's still quite relevant...

Also, found some info from the howstuffworks website we could transfer onto ours - the little animation thing at the bottom is pretty much all you need to look at i think...
