EcoSUND is A.M. Acoustic’s own unique sound absorber, developed together with acousticians and suppliers for raw material in 2010. All production takes place in Sweden, in the county Halland.
EcoSUND är kärnmaterialet som alla Akustikmiljös produkter är uppbyggda av. Vissa produkter kläs med textil eller akustikduk. EcoSUND is the core material that all A.M. Acoustic’s products are made of. Some products are covered with textile or Acoustic Nonwoven. EcoSUND products are available in thicknesses 20, 40 and 50 mm and the colour white, black, grey and brown.
EEcoSUND is completely free from adhesives and therefore does not emit no emissions or gases. The measurements for the emission meet the requirements according to SS-EN ISO 16000-9: 2006 for TVOC, formaldehyde and ammonia.
The structure of the absorbent means that the fibers are both moisture-resistant and thus cannot mold, and doesn´t release dust or anything like it which can cause allergies.
Sound absorption is a complex process. Simply explained, the sound waves entering the EcoSUND material is slowed down when it collides with the fiber composition and is converted into heat energy - then it becomes quiet. The result of this gives a reduced sound.
Since the launch, EcoSUND has been highly appreciated by customers and acousticians because of its good ability to absorb sound even when the sound comes from steeply incidental angels. EcoSUND has even absorbing qualities over the entire spectra.
EcoSUND gives positive effects regardless of whether you use it on the ceiling or wall. But, to get the best possible acoustic effect, it’s recommended to take the help of competent people to make the right choice of products and placement as part of getting the perfect sound. This competence is available at A.M. Acoustics.
