Err, double post.
My daddy's a fireman and can do 10,000 push-ups!I will absolutely take a look at that this weekend. And nope, physics hasn't changed a bit since 83 (although my physique has, but I was born in 83 and that's a different story).
No worries at all about insulting, I'm here to learn as much as possible. Just for those wondering, my background is basically what my dad has taught me, and research I do on my own. I've been interested in flight and aircraft design since I was a kid. I won an invite to NASA's Space Camp program in 6th grade for a Space Craft design program, but was unable to go due to money. Initial intentions in junior high and high school were to go through the UC Davis Aeronautical Engineering program, but I generally had problems focusing in school as it was usually too easy, and bored me. I usually aced tests, but didn't do homework or class work. Then I also started slacking off when I started getting paid to jump motocross bikes my senior year.
My dad's background is a masters in physics, and 30+ years designing power supplies for everyone from NASA and the military, to Honeywell home thermostats. I can't say (and don't know everything hes built), but I know the F-16 gyroscopes used power supplies he's designed. He also is a hobby engineer, building a robotic vacuum 20 years ago that relied on radar to map out the house. He's also been working on a voice recognition/simulation program. His goal is realistic sounding human voice, and is using FEA and Navier Stokes equations to do it instead of the common Fourier transform equations (which result in the metallic sounding "Steven Hawking" voice. I have a file that I'll ask him about sharing, that simulates air blowing through a tube, and it actually sounds real. He said it took 500 billion calculations per file, and there are 3 different tube length/diameters. His goal is to as accurately as possible model an average human lung set, voice box, throat, mouth, etc, to attempt to make the simulation indistinguishable from real human voice.
He actually recently left the company he was with for 30 years to start his own project, although I can't yet divulge what his new project is, it is something that most people would assume is straight out of a movie.
This is the list as of right now.
Dynamat xtreme - 1 12"x12"
GTMat Pro 50 Mil - 2 12"x12"
GTMat Ultimate 80 Mil - 1 12"x12"
GTMat 110 Mil - 1 12"x12"
GTMat Onyx - 1 12"x12"
Alphadamp - 1 10"x14"
SDS CLD - 2 6"x10"
Stinger Road Kill Pro - 2 6"x6"
Lightning Audio Deadskin - 1 8"x8"
StP Bomb - 1 sheet
StP Gold - 1 sheet
StP Silver - 1 sheet
StP Vizomat - 1 sheet
Peel N Seal - 1/3 Roll
Audio Tecknix
I'm at the limits of my budget right now, but there will be more things tested. I just need to wait for funds to catch up. Things on the wish list are Second Skins products, Cascade's products, Blackhole products, and Knu's products. I also want to try a spray on. Of course, if my motocross bike sells, this stuff will all be added to the list immediately.
Oh yeah!My daddy's a fireman and can do 10,000 push-ups!
Just kidding, sounds like you a pretty cool childhood.
Outstanding attention to detail!Ok guys. I want to apologize for the delays. There have been some things happening here that are out of my hands, and will continue to for the next week. As of right now, I have everything I need to start testing. The magnets are epoxied to the accelerometer board and are curing as I type this, however, it will be at least tomorrow before I can even try them, and possibly not until next monday. The current list of products is the same as the last one posted for now, and the die is ready to cut them now.
The reason for the delays are family medical. As I posted a page or so back, my mom had been in the ER. She was back in the ER last saturday for an allergic reaction to a new medication. My sister in law was also in the ER sunday night, monday morning, and admitted to the hospital monday night with valley fever. At this point, it looks like she'll be flown to UCLA today as her lungs are filling with fluid and they can't figure out how to stop it locally. I will get this testing done as soon as I can, just bear with me for another week or two. I will probably be able to work a little during the week, but weekends will be out until this is resolved.
As for updates, my dad will be in town tomorrow with another program he wrote to communicate with the scope. If I'm not in town, I'll post from my phone how it worked.
Also, I have a second method I am going to use to attempt to show long term heat/cold cycle durability. For those who don't know, I live in the central valley, where it is often over 100 degrees during the summer. And since I am mostly riding to work right now, my car is sitting directly in the sun, perpendicular to the travel of the sun. So I am going to pull my headliner, and put a small 1"x1" sample of each deadener on the roof of the car, in a small grid, and watch them over the summer and winter. I will take pictures every week, or more often if the results are more dramatic. However, this means I will need to cut of donations and any other samples on June 30th. Since all samples need to go in at the same time to be fair, this is how it has to be done. (I will begin vibration testing before that, next week depending on family circumstances, but no later than the week after that). For anything that is purchased or sent after that, I will still test them in the oven, and all current samples will be tested in the oven as well. I just think that the in car test is the best way to do this.
I will be leaving work early to work on this project (vacation time) and will get pics of everything up.
We appreciate the update, but as already stated by Jazzi and others, take as much tame as you need, family should come first.Thanks guys. Just didn't want to leave this hanging without at least an update to what was going on.
Dustin, depending on what goes on this weekend, I may be able to do a test of the measurement process, if your interested in checking that out.
I think I'm going to post raw data in this thread as it comes out. Then make everything pretty and post it at once after I get all the samples tested and start a thread titled CLD Testing Results, or something like that. I was struggling for a while with how to best present it, without getting a million posts in between me posting results, and I think that's the best option.
Take your time sir, we appreciate the tests and just wanna see it done right and if snags are hit or family comes first, so be it. We all have a pretty good idea about deadener, this will just give us another tool to make better decisions and possibly help the deadener manufacturers out as well to produce better product. Let us know if you need anything else.Thanks guys. Just didn't want to leave this hanging without at least an update to what was going on.

Chris, I agree, this is my expected outcome... Still, I appreciate you going through all of this, it is MUCH appreciated!!!I'm going to say this now, so people are ready for it. I believe the test results are going to be VERY close for the VAST majority of products. I think there may be some highs and lows, but I think similar products are going to be hard to tell apart. So close that this may become a game of pure cost, not even cost to performance.
