AcoustiPack EXTRA PC Case Insulation | 7mm Acoustipack Extra

AcoustiPack EXTRA

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. AcoustiPack™ EXTRA makes AcoustiProducts™ range of acoustic material kits more flexible, and can help to save money and waste when an entire kit is not necessary.
Acoustipack Extra Layers

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, while still remaining as thin as possible.

3-Layer Materials

In the 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 (>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.
