Product Description
NeoFill-HD is used for technical sound absorption. Its industry leading 150-200 PPI open-cell surface with activated carbon granules guarantees that sound waves are not reflected as an echo but can penetrate the cell structure unhindered. The sound energy is reduced in the cell structure, giving NeoFill-HD an excellent sound absorption capacity. NeoFill-HD excels at absorbing a wide range of frequencies due to its high density which has been formulated to improve low frequency absorption below 300Hz.
Granular activated carbon (GAC) has numerous applications due to its ability to adsorb and desorb air and gas molecules. It has been shown to exhibit unusually high low frequency sound absorption. This behavior is determined by both the multi-scale nature of the material, i.e., the existence of three scales of heterogeneities, and physical processes specific to micro- and nanometer-size pores, i.e., rarefaction and absorption effects.
