AcoustiPack™ ULTIMATE sets a new standard for PC soundproofing material kits, where maximum noise reduction is required in a limited space. This multi-layer acoustic materials kit includes 3 sheets; two 2-layer (4mm thick) and one sheet of Acoustipack's latest generation 3-layer materials, providing superb levels of noise reduction despite the thickness being only 7mm. This computer soundproofing kit is designed to reduce the noise emanating from noisy PCs with case sizes ranging from standard ATX, up to larger E-ATX and pedestal server cases used by gamers, power-users and small business users.
How Acoustipack Ultimate™ Layering Works
In this latest generation of Acoustipack, 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:
-> Acoustic foam
-> Acoustic barrier
-> Acoustic foam
-> Substrate (usually a metal sheet panel)
Sound energy first hits the upper foam surface of Acoustipack Ultimate. The upper foam surface is similar to the 2-layer construction Acoustipack, 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. Acoustipack™ 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.
