I am looking for the mathematical proof for the theory behind the transmission line box. Anyone here have a link or reference to a paper?

Jeff,

What I am looking for is how they generate the charts that are used, the actual math envolved and the associated field theory necessary to generate your own values. I am going to do a design project for my senior design course (electrical engineering) that involves monitoring with mics inside the box and analysising the results in Matlab. But, I am need of some more theory, I think I will end up going to the library and searching through IEEE documents Lord Rayleigh’s stuff and what not and go from there.

This is like the God Father of modern acoustics, without him and his work...we wouldn't have all the cool toys that we have today! :)

or someone else would have figure it out.....
