My Measurement Rig Progress / Purrin Reveals All!
Hands:
LOL, nice! Can we get pics from the side to get a better look at the coupler?
Marvey:
I know, I know, I should have posted pictures of my "semi-secret" measurement rig long ago. Many people, including Jude as recently at the Ann Arbor meet, have gone on rants regarding my not posting photos of my measurement rig or refusal to discuss my methods. I agree that this criticism is totally warranted. In my defense, I had my own myriad of reasons. Those close to me know exactly the reasons why I refused to post until now.
Quite a few Changstar members have figured out their own methods with great consistency and repeat-ability. The time is now right.
Here you go Hans:
I actually have a newer coupler with pinna, et. al. but still using this old V2 for sake of comparability to existing measurements.

I highly appreciate all the great information and photos Marv and Ultra! I think I can use these as my reference in approaching a solution for my rig as well! :)p1
And absolutely hilarious naming XD :)p13
Out of curiosity, is the inside of the enclosure filled with anything? Cotton wool or similar material? Would that even have any effect on the measurement?
Thank you all so much :D
Marvey:
I filled the inside with medium density open cell foam - to simulate brains. Use something squishy to avoid interactions between L and R.
Really, you could just put the felt / foam layer on top of a CD on top of a foam brick. I just made it look nicer and named it C.U.N.T. to establish "cred". We all know that stuff that looks nice, that is shiny white, and has a euro kind of acronym like G.R.A.S. or C.U.N.T. must be good.
Armaegis:
If you replace the word technology with machine, the abbreviation makes more sense... :D
