Who We Recommend
The new range of AcoustiPack sound-proofing kits has been designed with our customer's pockets and greater flexibility in mind! As a result, we have introduced AcoustiPack EXTRA Sheet (7mm), which is a single large sheet of our latest generation 3-layer acoustic material (as found in ULTIMATE). This sheet is ideal if additional materials are required for a particular project, and the space allows for a 7mm sheet to be added. This product makes our range of acoustic material kits more flexible, and can help to save money and waste when an entire kit, such as ULTIMATE or LITE is not necessary.
Perhaps best suited where there is enough room to fit a sheet of acoustic materials that is 7mm thick. Best fitted directly opposite a noise source, such as adjacent to the CPU fan on the inside of the case side door panel, or on the floor directly below a noisy HDD cage.
3 Layer Materials
In our latest generation of 3-layer composite (Patent Pending), the dense acoustic barrier layer has been 'suspended' away from the substrate in the center of the acoustic foam. The construction layering is like this: (noise source) acoustic foam -> acoustic barrier -> acoustic foam (then the substrate, which is usually a metal sheet panel).
Sound energy first hits the upper foam surface, which is similar to the 2-layer construction, in that it is a low-reflective soundproofing material that is particularly effective at absorbing high frequencies. The sound energy then encounters the central suspended barrier layer, which is decoupled from the substrate. This high-density high-mass layer acts as an acoustic barrier mass to the transmission of energy through the material. The 3rd layer of foam acts to suspend the barrier layer a small distance away from the substrate. We have found from both small scale impedance tube and larger scale reverberation chamber acoustic tests that the 'suspended' central acoustic barrier effectively increases the absorption of low frequency noise (<1 kHz). This may well be a result of the 'mass-spring effect', where low frequency energy is absorbed by the sound 'moving' the layer when it is excited by certain resonant frequencies.
The 3-layer materials are attached by a supported self-adhesive directly to the substrate, and have a damping effect on panel vibrations. (Hit the side of your PC once fitted, and you will hear a dull 'thud' sound).
The 3-layer materials in the AcoustiPack kit range are 7mm thick. We also manufacture these composites up to 13mm thickness (and over if required) for manufactures and OEMs. For example, they have been very successfully used in servers and server cabinets, and tested by many different organizations all over the world since they were first developed.
Note: Please take care to read the installation recommendations before installing this product. These materials are installed at the owners ow risk.

This product is very wonderful. You need to start with your expectations at a minimal and then be surprised at how much sound this isolates. In tests at a few reputable websites, they said the ultrapack reduces noise approximately 7 dB. However, the thing I like the most about it is that it absorbs a lot of the worse ends of the sound spectrum, i.e. high pitched fan noise, fan clicking, capacitor whine, etc. It leaves only a gentle, low hum if you have your decent quality fans in your system spinning at 50-75%. As someone already mentioned, its not going to make a 3000k rpm fan inaudible, but if you have quieted your system as best you can and you want 7dB less noise, this is the product for you.

Hands down the Best Sound Dampening Product!!!05-05-2011
Reviewer: TOOdamnFRANK (3)
This product arrived on my door step along with the sound dampening kits / materials from Modright and Lian Li and it blows both of them out of the water. According to my trusty Radio Shack SPL Meter it cut the sound levels by about 9db at a distance of like 15 feet. Since the rig is to be used in a music recording studio every DB counts. The density of this product alone will help stops vibration resonance, and then when you factor in the honeycomb top layer that eliminates a lot of higher frequency fan / air pressure noise this thing is a real winner. It is 7mm in thickness which is only 1mm shy of being twice as thick as both of the other products, but even if you doubled up on the other types / brands you still wouldn''t have the middle rigid layer that this company has inside that does a great job at stopping vibration noise in its tracks. This stuff rocks and is actually worth the premium price tag unlike a lot of other stuff. The only possible downside I can see is that it is just about the exact thickness of standard brass motherboard stand-offs, so i would not advice using it under your boards as per the instructions, but then again I personally wouldn''t use any under sound dampening materials under my mobo back side for obvious reasons.

First thing I noticed is how heavy this stuff is. Does it work?? Yes, is it going to make your PC silent by itself...no.. But if you are trying to eek out every bit of noise reduction you can then this stuff will help you.

If you want a way to make the air borne noise in your PC not make it out, this is the stuff to use. It works really, realy well. Very think and dense, really takes care of all the noise. I would recommend this to anyone that is looking to make their PC quieter.
