Sound absorption means that the energy of the sound is converted into mechanical vibration and/or heat energy. Sound absorption is expressed through the sound absorption coefficient (alpha) or the class A to E according to EN ISO 11654 and NRC/SAA, and according to ASTM C423. Expressed in another way, the closer you get to an absorption coefficient (alpha) near 1.0, the more powerful the “mute effect” in a given material.

Ucomposites has a vision of becoming leading on acoustics glass fibers for exhaust emission control, nonwoven and specialty glass fiber products. We have access to the best competences available both through own tests as well as through partnerships with international acoustics companies and universities. This means that we can offer consulting and advise to our customers on how to develop their products to obtain their required sound absorption targets.
