Joe I'm looking to try to hold down noise in the system I'm just strating to buy for. Along with low dba fans I've been looking at these sites for materials to line the case with to deaden the noise.
www.b-quiet.com They make foam to deaden noise in cars so it's flexable and should work in tight spots. I'm most interested in what the call L-comp, a composite.
www.mcmaster.com Here I'm looking at egg shell foam. It's listed under noise reduction in the last group in the right hand colum on their front page.
So not only am I looking forward to your article I'd love to hear your thoughts on these products.
