AcoustiPack™ EXTRA Sheet MAX Soundproofing Sheet (APExtSM)
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 MAX (12mm), which is a single large sheet of our latest generation 3-layer acoustic material, 5mm thicker than found in
AcoustiPack ULTIMATE. This sheet is ideal if additional materials are required for a particular project, and the space allows for a 12mm 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 AcoustiPack ULTIMATE or
AcoustiPack LITE is not necessary.

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.
AcoustiPack ULTIMATE 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).




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).
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 (<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.

Suitability:
Design for Large PC case, powerful PC case, gaming PC case or pedestal server case as well as cabinets, enclosures and multi-purpose..
This pack is suitable for any PC.
Perhaps best suited where there is enough room to fit a sheet of acoustic materials that is 12mm 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.
