In the construction field the Acoustics Laboratory certifies the sound absorption characteristics of sound-absorbing materials, suspended ceilings and interior components. In the industrial field, Z Lab certifies the sound absorption characteristics of systems/industrial products, such as manufacturers of furniture rail and air.

The new trend of many leading companies in the field of sound-absorbing material is to offer their customers not only a sound-deadening product, but also a complete and exhaustive solution to their problems of sound or noise. Part of this task is often accomplished by providing their designers certified acoustic solutions readily available to be placed within projects more complex and articulated. Through its reverberation room, Z Lab performs sound absorption tests according to EN ISO 354:2003 (Measurement of sound absorption in a reverberation room).
