One Side – OS

One Side – OS

One Side “OS” panels are sound absorbing, composed by metal structures, and coated with textile on one side only; They are made for wall and ceiling mounting.

Sound absorption coefficient

The sound absorption coefficient (α) indicates the amount of the sound energy absorbed by a material. Its value varies depending of the frequency with a range between 0 and 1. A material with a sound absorption coefficient α = 0.65, is equivalent to say that it is absorbing 65% of the sound energy at a certain frequency. In other words, only 35% of the sound energy is reflected.

The Average sound absorbtion coefficent OS panel αW = 0.65
