Diaphragmatic Absorption: Time Tested And Proven
Acoustic Fields has taken the standard diaphragmatic absorber technology and improved it in three major ways. First, the front wall in all of Acoustic Field’s diaphragmatic absorbers is not just a single wall. It is a dual wall structure that has been designed to increase the rate of absorption by increasing the level of energy that is slowed down before entering the internal cabinet fill material. With a dual wall face that is designed with sympathetic vibrational technology in place and having both dual wall, front panels that are designed with the proper density and air space between them to insure maximum movement in sympathy with each other, greater absorption rates and levels are achieved.
Activated Carbon Diaphragmatic Absorption
How It Works
When sound pressure energy strikes this dual wall, front face assembly, it is slowed down by a factor much greater than a single wall. Secondly, cabinet rigidity and density has been increased using multiple layers of materials with different densities to insure maximum cabinet rigidity, so that the front dual wall construction is encouraged to vibrate. Viseo elastic compounds are used between each cabinet layer to insure that vibrational energy is minimized from the cabinet itself. Finally, the internal cabinet fill of standard building material, mineral fibers, has been replaced with activated carbon. Activated carbon is a fancy name for charcoal. Activated carbon has a high degree of porosity which contributes to its high rate and level of absorption over standard building type insulation. The rates and levels of low frequency absorption created by Acoustic Field’s activated carbon diaphragmatic absorbers have never been achieved until now for a commercially available product.
Features
Our ACDA -10 is our flagship, activated carbon, broadband, diaphragmatic absorber with low frequency absorption from 30 Hz.-100 Hz. The face of the unit can be used to support one of our foam absorber thicknesses or one of our mini-diffusors in our MDP line. Units are designed with rigid side and rear walls and a dual wall, front panel construction that increases diaphragmatic action. The inside of each unit contains our activated carbon filters which increase the unit’s Q value through acoustical compliance enhancement. This activated carbon filter process is unique to low frequency absorbers and is patent pending. Solid wood oak, maple, and walnut frames are available along with numerous other finish options. Each unit measures 60″ tall, 24″ wide , and 10″ deep. Each ACDA-10 unit weighs 240 pounds.
