Some applications require the guarantee of good sound proofing. Such is the case for animal housing facilities in research laboratories, for instance, or hospital operating theatres and recovery rooms.
The lowering of the acoustic level is the interior wall’s capacity of reducing the volume of sound between two adjoining rooms, or its resistance to the transmission of noise.
Acoustic partition walls with metallic or compact laminated facings bear a high acoustic level lowering index due to their special design.
