I had hunted through all the files I had saved and hadn't found anything... http://www.patchn.com/index.php?option=com_fireboard&Itemid=90&func=view&id=324&catid=2 Ron explained it once. I think it had something to do with patching things up. It's probably in the archives. Oh Here it is (http://www.patchn.com/SMF/index.php?topic=919.msg7023#msg7023). It is a reference to patching something. I was originally on the net via AOL and talked in PC chat rooms, my name was patchnman I was custom building PC's at that time and built a website for that purpose, I used patchn for the name because it was short and at the time people knew me by my AOL screenname. ... http://www.patchn.com/index.php?option=com_fireboard&Itemid=90&func=view&id=323&catid=2 After 62 viewings, I must conclude that only Ron k5new why or what it meant Shame really ... http://www.patchn.com/index.php?option=com_fireboard&Itemid=90&func=view&id=322&catid=2 I know Ron can't tell us, so did anyone know what the website title meant ?... http://www.patchn.com/index.php?option=com_fireboard&Itemid=90&func=view&id=321&catid=2 The product that I was looking at comes from Mascoat and its called Delta~dB. When I talked to our rep the claims he presented were 10-15 dB reduction. That was with a 40 mil coating, best case. 10-15 dB is a fairly considerable amount. Were the numbers you got maybe meaning reduced by 6-8 dB or to 68%? Most of the applications this is used in are insulating the inner hulls of boats and ships. They have some case studies on their web site http://www.mascoat.com/index.php I believe they are based out of Tex... http://www.patchn.com/index.php?option=com_fireboard&Itemid=90&func=view&id=320&catid=2 Rob Interesting in that project am working on is evaluating a paint type product that is supposed to be good thermal and noise "insulator" ie claimed 68 dB sound reduction (???) not sure about the number and how they made the measurement but we are mostly interested in the heat transfer and insulation capabilities. Stuff is ceramic based sold by outfit in Texas. Am willing to share data (subject to it's being Top Secret blah blah blah) Let me know the stuff you have please.

Received a Bender battery / DC bus ground monitor alarm relay unit. Looks pretty good. Was going to test on battery we had on hand but we sold the battery so now need another guinea pig. Will use Bender on electric truck intend to put together - think 325 VDC battery will be good test.

My priorities have been "readjusted" lately. Bigger projects to play with. Still haven't been able to get all the testing done on either the sound or the temperature. Most of the sound testing has been coming back as adequate for what we want. Enough so that we may not be using the sound reduction coating at all. I believe we have scheduled an industrial hygienist to come in sometime this summer to give us an official documented tests confirming t...
