I don't think that wearing out is an issue with the sound deadening material, since it is running well within it's elastic limits, and the friction is molecular rather than the coulomb type, unless this material is fundamentally different from most materials.

Noise canceling is what I meant! Obviously, I mean outside noise, not the sounds coming from whatever the headphones are plugged into. ;) Was a typo due to not enough coffee yet today. ;)

@Elizabeth: Noise cancellation head phones ? Wow are there any of those available in the market ?

Great idea for the noise-cancelling earphones, William K. I wonder if that is a viable application.

Too much friction

Too much friction can damage the sheets and seeing the utility, these won?t come cheap, and if you stay in a place where there?s too much noise, these sheets will wear out pretty quickly. We want a solution that is cheap and at the same time creates a silence wall.

Once this material is protected by a patent it would be interesting to have a report on the details of just how it does the job. It just popped into my mind that it may also be useful for covering the outside of a set of erphones to block out ambient noise without having to be so big and tight. A potential secondary use of the material.

I wish you luck with your soundproofing, bob from maine. I have very limited experience with soundproofing but I know it's not very easy without a lot of material. I was also impressed by the apparent performance of this material, so if it works like it does on the video and as advertised, it sounds like it would be a great solution for you.

That's interesting, William K. I didn't think about the flammable issue. Perhaps that's something to bring up with the company. It certainly wouldn't be a good idea especially for hotels but I wouldn't think so for other buildings as well.

I am sure you're right, Nancy! I am sure lots of hotels would benefit from this sort of thing. I used to work in a hotel delivering food-service orders and I know that hotel for sure could've been served well by some soundproofing considering some of the things I heard when walking the halls.

tt, the concept is not new. Years ago, back in 1974, I think, I was evaluating the effectiveness of a mastic-paper laminated acoustic deadening material that worked on the same principle. But the stuff was too heavy and too expensive for most cars. But the same principle, turning the noise into heat by means of friction, was at work. The other limiting factor was that the material was quite flammable, which would be a problem in hotels.
