Vibroacoustics/Statistical Energy Analysis

four_4_f

Like Robert Frost, I have miles to go before I sleep, and all because I took the road less traveled…

This is a long-term work-in-progress…

I am including SEA in my Matlab GUI package.

The functions can be accessed via:

vibrationdata > Miscellaneous Functions I > Acoustics & Vibroacoustics

I am using textbooks by Lyon, DeJong, Wijker, Norton & Karczub, along with AutoSEA and VAPEPS manuals.

I am compiling SEA parameter equations scattered among various references into a single document.  He is my result so far:SEA_parameters.pdf

Please feel free to recommend additions or corrections.
