The importance of acoustics

Acoustic correction is a necessary part of creating good indoor environments

This allows you to achieve a high level of acoustical comfort without having to use ceilings with dimples, perforations or holes. The acoustical ratings of ROCKFON products have been tested in independent and certified laboratories.
