Time Tested and Proven: Diaphragmatic Absorption
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.
Two Front Walls Working Together
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.
Activated Carbon (Charcoal) Lowers Cabinet Q Value
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.
Our ACDA-5 unit pictured on the left is our broadband absorber that can now be positioned on the wall. It is a perfect partner with the MDW-13 pictured on the right. Absorption begins at 50 hz. and goes through 6,300 hz. Our proprietary foam face behind the fabric covers all frequencies above 125 Hz. and our activated carbon diaphragmatic absorber brings up the rear to lower our absorption range to 50 Hz. Numerous different fabric color options are available along with numerous stain and wood choices. Our bass wood with gun stock stain is shown here. The ACDA-5 measures 10″ wide and is 8″ deep. Units come in 48″,60,” or 72″ lengths. Each unit weighs 30 – 50 pounds. They can be positioned horizontally or vertically on any wall surface.
With broadband absorption from 50hz.- 6,300hz., one can now position low frequency absorption throughout the room and have it off the floor. Placing broadband, low frequency, absorption throughout the room is best for even low pressure energy control. Units can be positioned vertically or horizontally. The many different fabric color options make coordination with existing room decor easy and the numerous wood and stain options add to this same decorating flexibility.
