Acoustics in the venue will be affected by following factors:


Sound Absorption

Three types of sound absorber come together in Knauf acoustic systems. All trays or plates act as membrane absorbents for subtle vibrations. Resonances occur within the frequency range of the hole acts as an absorbent moderate. In addition, an absorption in the high frequency range is achieved through the passage of sound in the rear acoustic fiber. With these features, sound absorbency can be provided in frequency range. Thus, all requirements for modern spaces with perforated sound absorbers will be asked to cast set in a perfect way and accessible to them.

Sound Absorption Degree α

Sound absorption degree α is the ratio of the sound energy of the reflected sound energy occurs. Full reflection α = 0, α = 1 full absorption.

Reverberation Time

Sound absorption in a space defined by the reverberation time. This volume gives voice publications of the time period of 60 dB after the recent fall.

The Distribution of Sound

Perforations on drywall provides both sound absorption and distribution of sound. By the perforated structure of boards, distribution of sound makes different impact than imperforated drywall.The sound of waves hits the edges of the hole breaks and expenditures in different directions. Thus space remains in an amount of sound energy , thereby creating a more comfortable acoustics. Not only distribute audio originating from a perforated plate construction also better it absorbs . This is the possibility of absorption of the sound waves further improve holes lies in the dispersion of a large.

The Reflection of Sound

By the hardness of gypsum board, it can return some sound waves. This can be provided in imperforated plate and around the hole. Perforated plates reflect stronger but they only attenuates sound waves like membrane absorption.

Sound Insulation

Gypsum board can insulate the metathesis between the rooms by it's high intensity properties.

If the boards are reninforced by mineral wool, they can increase the insulation values.

Sound insulation regulations are determined according to EN 20140-9 document and DIN EN 20140 - Chapter 9.
