Absorption materials are used to control sound within a space. Acoustically absorptive materials are typically rated with an NRC number. Some materials may also be rated with a CAC number (usually ceiling tiles) and yet others may be rated in Sabines. Absorption panels can be used to control harsh reflections, reduce reverberation time, or eliminate echo. Absorption panels can also be used to reduce the propagation of sound in otherwise open areas (i.e., down a long hallway). Acoustic absorption panels come in many shapes, sizes, and materials.
BASWAphon is the best for acoustical noise absorption. The BASWAphon acoustic system is an innovative, mineral-based, patented modular product line designed for controlling sound reverberation time. The system is comprised of a pre-coated mineral fiber panel which is adhered onto a hard surface (cement, plaster fiber panel) and is then seamlessly coated with a micro-porous coating mass.
How BASWAphon works:
High frequency sound absorption is accomplished by allowing sound wave energy to pass through the micro pores in the finished surface thereafter dissipating into heat energy in the mineral wool.
Low frequency sound absorption is accomplished by sound wave energy hitting the mass of mineral particles on the finished surface, causing the finished "skin" to vibrate in a diaphragmatic action against the mineral wool backing which creates a spring action, again transforming sound energy into heat energy in the mineral wool.
