AcoustiPack MAX | AcoustiPack Extra Sheet 12mm

AcoustiPack EXTRA Sheet MAX

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, is not necessary.

AcoustiPack Ultimate Features

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

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).

AcoustiProducts 3-layer acoustic material design

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.

The 3-layer materials are attached by a supported self-adhesive directly to the substrate, and have a damping effect on panel vibrations.

Acoustipack Max EXTRA Suitability

This pack is suitable for any PC. Acoustipack Max 12mm Sheet is 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.
