Just saw a link come up on Google ads
http://www.mutemat.co.uk
It claims to be a better sound absorber than acoustic foams because it is made with very fine fibre, which gives it a lower density & smaller pores. It seems like it's only just gone up - google search only returns one correct match, for someone who used it and noticed a difference. I wonder how it fares in already-quiet systems?
It's only available online right now, £16 for 2 large and 2 small sheets. Not bad if it works as well as they say. There is one with acoustic barrier mass coming out shortly (should be comparable to AcoustiPack?) and one that watercools the processor at the same time - should be interesting!

The price is OK, 30€ shipped inside EU. So really not that expensive, cheap enough to just test it without actual need. Would be interesting to see a review of it though prior to ordering. It doesn't look like the conventional acoustic foams. Would be interesting to see a closeup of the structure.
The only downside is, that the online ordering requires payment via PayPal. Just don't like using it.
Edit: Just noticed on their links page, that they have a link to SPCR and a guide about "how to make a quiet pc" coming up

I think it looks like this without the green stuff at the bottom. THis is a pic of the plus version btw...

According to the (very basic) acoustics course I took last year, this might be the hot ticket. We didn't much consider the practical applications in the course, but one of the key points on sound absorptive materials was:
Fibrous structure - As the sound waves hit the fibres, they are supposed to rub each other and dissipate sound as heat...
Low density - (Although I can't remember any numbers right now)
All other damping sheets I've seen are ... foam. They don't look fibrous at all, they look just porous. (Is this how porous is spelled?)

Yes. Porous.
I sent an email too, let's see what they come up with. My PC is bare steel at the moment and I think it could do with some carpet.
Edit: the FAQ got changed to make it clearer that you shouldn't cover disks with the stuff.

I added the bold for scanners, but that comment might tempt some people to make good(?) use of the leftovers - just make sure you follow the Drive Decoupling Safety Manual. And don't stick it on the drive itself unless you want it permanently quiet!MuteMat FAQ wrote:We would NOT recommend using MuteMat directly against hard disc drives (HDDs) as a method for vibrational noise dampening (although it is quite effective!), as these components normally require cool air circulation around them or good contact with metal for direct heat transfer.

It is called the absorption coefficient. Scale: 0 to 1. It is on the graph plotted vs. frequency.Do you guys find the sound absorption rating or something on the site? Cuz i thought you could compare dampening materials by some sort of rating, going from 0.00 to 1.00?
Well the thing wrong (or iffy) about the graph is: "Absorption Coefficient Normal Incidence"
I think this is the test performed in an acoustic impedance tube where all the sound waves strike the material perpendicularly. However in a normal case or room or any other real world situation, the sound waves will strike the material at random angles. The difference is that to test random incidence, you need a special room and you need to line most of it with the material... So it is much more relevant but also much more complicated and expensive to do.
As I remember, even though the numbers for normal incidence are not useful for random incidence, different materials can still be compared. I think that 99.9% of the time one material that is better in normal incidence will also be better in random incidence. So even though the graph is not directly applicable, it is an indicator for the material (if they are honest about the data on the graph).

MuteMat Plus
With regard to MuteMat Plus, we are currently in the process of evaluating the performance of several different high density layers to determine which is 'the best one for the job'. Once the material has been chosen we will then be able to determine the price, and also a time when it will be available. Just keep an eye on the web site, as the information will be announced there. Hopefully by the end of the week or early next week I should be able to give you a rough date and price.
Once MuteMat Plus is available we will be looking to sending both these products for review. Again, information will be put on the website closer to the time.
If you have any questions please contact us - [email protected] or visit our site http://www.mutemat.co.uk
We have also included a close up picture of MuteMat on the information page. Hope this helps.

Hmm I wonder how it would compare with this combination:

Item#: 9709T19

Weight question
Mutemat universal is very light due to the microfibres. 0.3kg. Mutemat plus uses a heavy second layer so the kit weighs approximately 2kg.

Looks interesting. I'll soon be taking the plunge (that is, when I get round to buying a new pc) and padding up. I'm now torn between Nexus's DamTek foam and this MuteMat. Who has experience of either? The website also pointed out that the fraying of foam can cause dust-related problems. Anyone know anything more about the DampTek in relation to this? The Nexus is white, meaning that I can get some UV lights to make the thing look funky. If I get the black MuteMat I'll probably settle for some slightly more expensive neon lighting. Ooooooooooh, too many options!

Thanks for the question, sorry for the delay in replying:
How Thick Are the Kits?
The standard MuteMat material is 19mm thick and the kit weighs about 0.3Kg. For the Plus kit we add a 1.5mm High Density barrier layer which is designed to help stop the case from vibrating and also act as an acoustic barrier and the combined thickness is about 21.5mm, this kit weighs about 1.8Kg.
Do these Materials Compress?
The 19mm thick MuteMat layer has a non-woven, micro-fibre structure which makes it VERY compressible. This enables it to be fitted more easily to the case and so it can be applied to narrow areas of the case where 19mm would not fit. The barrier layer in the plus kit is high density, and will not compress.
Does Compressing the Material Reduce Performance?
This material is VERY compressible, and can be compressed to less then 1mm. If the material is GREATLY compressed, this forces the micro-fibres closer together and can lead to a very slight loss in absorption performance. We minimise this loss by the ultra fine structural composition of the material.
Hope this helps. If we can help you further please contact us.
Regarding sending sample kits to Silent PC Review, this should be happening in the next few weeks. I will put a post on this thread when we do.
