Sound protection and sound insulation with Knauf AMF

The perfect acoustic

Our claim for ceiling systems is none other than to create the perfect room acoustics with timeless, elegant design. We flexibly adapt your space (also retrospectively) to current acoustic requirements and changes of use.



A ceiling can make a significant contribution to room acoustics. The traditional choice for architects of smooth materials with low acoustic absorption or perforated materials with high sound absorption is now in the past.

AMF Acoustic ceiling systems combine smooth surfaces with a particular acoustic performance to create the ideal acoustic environment. A choice of different acoustic properties from the AMF Acoustics range of ceiling tiles ensure that specifiers can choose the right option.

An AMF Acoustics suspended ceiling is able to change offices, meeting rooms, corridors,class rooms, auditoria and cinemas into spaces of good speech intelligibility. Concentration and attention spans are increased, enhancing work efficiency and well-being. The new technology of AMF Acoustics ceilings creates a peaceful environment, and offers the additional benefits of excellent fire protection, high light reflectance and easy installation.

The Knauf AMF room acoustics calculator

Achieving optimum room acoustics has become one of the most important construction requirements. Thereby, different demands are placed on the ceiling depending on the rooms use. A suspended ceiling is of great importance, especially for controlling the reverberation time according to the rooms use.

To help you in selecting the correct ceiling, the AMF acoustic calculator is now available with which you can easily carry out reverberation time calculations and plan room acoustics.

Parameters of sound

Sound absorption

Sound absorption

Sound absorption is responsible for the “audibility” in a room. How “reverberant” a room seems or how loud a source of sound appears is dependent on the sound absorption. How do you define “sound absorption”?
What we understand by this is reducing the sound energy in a room through sound waves losing energy on component surfaces. The energy of the sound waves is absorbed or reflected by the enclosing surfaces, as well as objects and people within the room. The correct sound absorption ensures that the sound in a room is perceived as louder or quieter. The ability of a material to “swallow” sound waves depends on the materials properties. Porous, open-cell or perforated materials normally absorb sound very well.
“Good audibility” in a room describes the conditions that enable the best possible transmission of a sound source to the listener.

Sound attenuation

Sound attenuation

The ceiling naturally contributes significantly to the transmission of sound between rooms. It is therefore necessary to achieve the highest possible values of sound attenuation for the ceiling. As opposed to sound absorption this is not a problem of optimizing but rather one of maximizing. AMF Sound Insulation Ceilings offer technological leadership by achieving sound attenuation values in excess of 40 dB.
