When a sound wave strikes a surface of a

material, it is either reflected or penetrated

into the material. If the acoustic impedance of the

material is too high, the sound wave is reflected.

If the acoustic impedance is low, sound waves enter the

material.

FiberAcoustic^® is a novel nonwoven sound absorber

specially developed for optimal acoustic performance due

to tuned acoustic impedance.

The FiberAcoustic^® acoustic impedance is low enough to

ensure that minimum sound is reflected and accurately

high enough to ensure that maximum sound energy is

converted into heat - while letting a broad spectrum of

sound wave frequencies enter the material.
