  Wood Fiber Acoustic Board standard sizes are 1200mm x 600mm and 1220mm x 2440mm. And the size can be customized.The standard thickness is 15mm,20mm,25mm.   1. Wood Fiber Acoustic Board Materials Description: Base material are made of natural wood wool and cement.We use different hot-press to reach different density and sure its ventilation. They are options for customers to match the requirement of the building sites.   The Suggestion Of Indoor Decoration On Wood Fiber Acoustic Board            If the rear wall backs up to a control room and/or class rooms it is recommended that before applying acoustic material the wall be covered with one layer of a gypsum board material (drywall) nominal dimension 5/8" thick. This must be installed directly onto the concrete CMU block or AR Steel with NO air space.      All doors should be ballistic and acoustically rated. If there are windows they should be comprised of a single pane ballistic or a duel pane acoustically rated laminated glass.   For Side Walls - it is recommended that the side walls be treated with a two-inch (2") soundboard with a density of no less than four-pounds (4lbs) per square foot. The side walls need to be treated from the rear wall to at least seventy-five percent (75%) from the furthermost firing line to the bullet trap. The soundboard in order to be effective needs to be backed by a minimum of two inches (2") of wood wool sound dampening wall and ceiling Panel product with a nominal density of no less than two and one-half pounds per cubic foot (2.5 pcf). All materials need to be UL approved as to fire, flame spread and smoke developed.   For Safety Ceiling - the safety ceiling should be treated with one-inch (1") soundboard with a density of no less than two-pounds (2lbs) per square foot. The soundboard needs to be backed by two inches (2") of wood wool cement soundproofing panel based insulation product with a nominal density of no less than two and one-half pounds per cubic foot (2.5 pcf). All materials need to be UL approved as to fire, flame spread and smoke developed.   2.The Noise Reduction Coefficient (NRC) Of The Wood Fiber Acoustic Board                Chart 1 below compares the Noise Reduction Coefficient (NRC) of wood fiber acoustic board that have been used on indoor environment. Most of these products exhibit a low NRC in the critical frequency bands below 500 Hz. Our product shows an NRC of 1.20, significantly higher the next highest NRC 0.60 of acoustic tile. For years acoustic tile has been installed in indoor environment with very little to no benefit. The benefit of acoustic foam products is also suspect as little is known on how they perform under the influence of intense sound fields found on indoor environment. And rubber products are not represented as-to-date, as no rubber manufacturer has published NRC ratings from an accredited laboratory. It is felt by some that rubber products actually heighten the noise and pressure in a indoor place. There is also measurement and comparison data that also points to that supposition.   3.The Reverberation Time Of Wood Fiber Acoustic Board                Chart 3 below shows a Reverberation Time (RT60) of 5.39 seconds in all octave bands from 50 Hz to 20,000 Hz before treatment of the Ft Lewis, Sound with the System, and a Reverb Time (RT60) of 1.08 seconds in all octave bands from 50 Hz to 20,000 Hz after treatment of the Ft Lewis. The Reverberation Time (RT60) was arrived at by averaging sound positions at the 7, 25, and 50 meter lines, respectively along with fixed positions in the center of the range at the 25 meter point.     Small Ranges Are Particularly Susceptible To Wood Fiber Acoustic Board                Chart 4 below shows a Reverberation Time (RT60) of 2.54 seconds in all octave bands from 50 Hz to 20,000 Hz and a Reverb Time (RT60) of 0.69 seconds in all octave bands from 50 Hz to 20,000 Hz after treatment.       Chart 5 Below Shows A Generic Comparison Of The Reverb Time (RT60)        In an indoor treated with wedge foam, PEPP, 2" Rubber, and the System. It can be seen that effectiveness of the PEPP, and 2" Rubber is moderate at mid and frequencies, a steep rise at high frequencies, and almost nonexistent at the critical lower frequencies. The system treated range shows an RT60 of less than one-second (1 sec). As Reverberation Time (RT60) is a natural amplifier, if you think of the sound of your car alarm turning on or off in an underground parking versus outdoors, it is easy to see how important reducing the reverberation time in a indoor place is.         4.  Wood Fiber Acoustic Board Installation Method.   Method 1: Installation Into The Wall With Wooden Keel. The lengthways and transversal wooden keel need to be install into the wall with the nails. The wooden skeleton should be installed before the Wood Fiber Acoustic Board . Put the Wood Fiber Acoustic Board to the wooden skeleton with nails and hit the side of the panel the upper body nailing.       Method 2: Installation Into The Wall With Steel Keel. There is still another way to install the wood fiber acoustic board , which is to use lengthways and transversal steel keel, The wooden skeleton should be installed before the Wood Fiber Acoustic Board . Put the the steel skeleton with clips and install the Panel.     5. Besides the high sound absorbing test, we have passed the Eco-protection test and Fireproof test, to ensure you to get the top quality product, and enjoy a safe,comfortable and low carbon emission way of life on wood fiber acoustic board .     CE, ISO9001-2008,BV and Alibaba supplier assessment.   6. Wood Fiber Acoustic Board Application: It's widely used at huge stadium, cinema, meeting room, office room, music hall, theather and work shops etc. any places where need sound absorption can use this products.      7.  Foshan Tiange Acoustic And Decor Material Manufacturer produce many kinds of acoustic products and acoustic movalbe partitions. located in the Capital city of Building Materials - Nanhai District, Foshan City.
