AIRFLOW RESISTIVITY OPTIMISATION

Airflow resistivity optimisation

The airflow resistance of an acoustical porous material is a significant property that determines sound-absorptive and sound-transmittive properties. The common misconception is that the density of the acoustical porous material plays an important role in determining the amplitude and frequency of the sound absorbed. However, as different materials with the same density can have different airflow resistivity due to the material structure, density is an inaccurate measure of sound-absorptive and sound-transmittive properties.

Each of our acoustic panels and bass traps employs its own unique porous absorber that has a signature airflow resistivity that is different from the rest. This is because the optimum airflow resistivity of one product may not be optimal for another. Our airflow resistivity optimisation is calculated from an algorithm that is based on empirically tested data. We also consider the anisotropy of the porous material in use.
