AcoustiPack™ EXTRA - Sheet (APExtS)

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.See technical details of our materials.

Product Code: APExtS


What's In the Box?
3-Layer Sheets:	1 (7mm ±10%)
TOTAL Number of Sheets:	1
Product User Instructions:	Included

Pack Dimensions
Sheet Dimensions: (WxD, ±1%)	457 x 431mm (18 x 17")
Total Sheet Area:	0.197m² (2.12ft²)

Other Details
Flammability Certificate:	UL94-V0 (UKAS Accredited)

This pack is suitable for:

Small Form Factor PC case, media PC case, Shuttle PC case.

Suitable for any PC.

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.

Companion Products

AcoustiPack™ EXTRA Foam Blocks - help to absorb unwanted noise from PC components. Image shows 3 black acoustic foam blocks. Click for more details.

You may also like to consider adding AcoustiPack™ EXTRA Foam Blocks (APExtB) to this product. This will increase the internal surface area of the acoustic materials, and help to absorb extra acoustic energy inside the PC or server case. More details.

Material Features

These soundproofing materials have been designed to achieve maximum acoustic attenuation over a broad frequency range:

High Transmission Loss

High transmission loss is the composite material’s ability to impede airborne noise.

High Noise Reduction Coefficients

High noise reduction coefficients is the composite material’s ability to absorb airborne sound energy with minimal reflections.

Damping

Damping is the composite material’s ability to attenuate structure-borne vibration on metals and other substrates thereby reducing reradiated noise.

Material Non-Flammability

The individual components of the multi-layer composites used in AcoustiPack™ sound-proofing kits are certified and UL-listed for low flammabilty.

The finished 2- and 3-layer composites (including the adhesives) have also been tested using a vertical burning flame test, and both 4mm and 7mm materials meet class UL94-V0. The acoustic foam material supplied in AcoustiPack™ EXTRA is certified to UL94-HF1.

These low flammability results more than satisfy BS EN 60950-1:2002 ‘Information Technology Equipment - Safety’ section 4.7 with respect to resistance to fire for materials inside fire enclosures.

You may like to check that alternative sound proofing materials also meet these stringent standards!

Multi-Layered Materials in AcoustiPack™ EXTRA

AcoustiPack™ EXTRA Sheet (7mm) is a 3-layer acoustic material. Comparative small and large scale acoustic tests with alternative single-layer PC sound-proofing materials demonstrate that AcoustiPack™ multi-layer materials are more effective and safer, whilst still remaining as thin as possible.

3-Layer Materials

3-layer materials. Image shows the construction of the triple-layer soundproofing 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 centre 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 absorbtion of low frequency noise (<1kHz). 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.

Image shows the suspended barrier layer in the centre of the 3-layer 7mm acoustic composite use in this product.

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 organisations all over the world since they were first developed.
