Description of the contents of this technical brochureIn this technical brochure, the frequency-dependent absorption values of all acoustic systems pertaining to the room acoustic prognoses from Knauf Gips KG as dependent on the perforation pattern, the construction depth and insulation layer are listed.In addition to the values in tabular form, the curve progression of the frequency-dependent absorption response is represented in a graph.For planar surfaces, the characteristic quantity for the practical sound absorption coefficient is the response between the octave frequencies of 125 Hz to 4000 Hz. Furthermore, the sound absorption coefficient αw is specified as a single value quantity in addition to an NRC (Noise Reduction Coefficient) for the products. The procedure for determination of the rated sound absorption coefficient is explained on the following pages. The American NRC quantity is determined from the αs values as an arithmetic mean value of the third-octave frequencies 250 Hz, 500 Hz, 1000 Hz and 2000 Hz, and rounded off and expressed to the nearest multiple of 0.05.The room acoustic quality for non-planar surfaces, which are surfaces where it is not possible to determine an exact acoustically effective surface, is not defined by an absorption coefficient but rather by an equivalent sound absorption surface. Accordingly, when selecting the absorber, it is necessary to ensure that the practical sound absorption coefficient or the equivalent sound absorption surface is specified.For the majority of the listed items the acoustic quality was determined by measurement in a reverberation chamber in accordance with a standardized test procedure. The results of the tests are compiled in a test certificate and can be requested from the Technical Advisory Service. The values shown in blue are projected absorption coefficients based on an empirical process performed on the basis of a large number of measurements in a simplified procedure as well as experience of the response of absorbent materials with variations in the construction depths, insulation material layers and perforation ratios of the surfaces.E3

IntroductionSound Absorption - Requirements for the Insulation Layer
7AK02.de Room Acoustics with Knauf
Definitions of the sound absorption coefficients following EN ISO 11654The building materials and substances used in a room can be sound reflective from an acoustical point of view, so that they have no or very low sound absorbing characteristics. In this case the rated sound absorption coefficient αw is practically 0.In contrast, there are materials that are highly sound absorbing. Should 100% of the impinging sound energy be absorbed, i.e. the sound energy is fully converted to heat energy, the rated sound absorption coefficient αw is practically 1. αs indicates the values of the frequency-dependent sound absorption coefficient measured in a reverberation chamber in third octaves. The practical sound absorption coefficient is formed based on this factor. αp are the values of the frequency-dependent, practical sound absorption coefficient made up of three third octaves. They are frequently used for frequency-dependent prognoses. αw is the rated sound absorption coefficient. It is independent of the frequency and specified as a single value quantity. The determination of the single value quantity is undertaken in accordance with the procedure described on page 8.Shape indicators as suffixes to the rated sound absorption coefficient provide some indication of whether an absorbing material is particularly effective in the low, medium or high frequency range.
The following indicators are used: ■ L, when the product is particularly effective in the low frequency range. e.g. αw = 0.60 (L)
■ M, when the product is particularly effective in the medium frequency range. e.g. αw = 0.70 (M)
■ H, when the product is particularly effective in the high frequency range. e.g. αw = 0.85 (H)
Combinations are possible. e.g. αw = 0.70 (MH)

The Knauf Raumakustikrechner (room acoustics calculator) is available for individual calculation when Knauf acoustic products are employed (currently in German only).http://www.knauf.de/profi/tools-services/tools/raumakustikrechner/

Notes on the documentKnauf technical brochures are the information documents on special topics as well as on the specialist competence from Knauf. The contained information and specifications, constructions, details and stated products are based, unless otherwise stated, on the certificates of usability (e.g. National Technical Test Certificate (abP) valid at the date they are published as well as on the applicable standards. Additionally, design and structural requirements and those relating to building physics (fire resistance and sound insulation) are considered. The contained construction details are examples and can be used in a similar way for various cladding variants of the respective system. At the same time, the demands made on fire resistance and/or sound insulation as well as any necessary additional measures and/or limitations must be observed.References to other documentsTechnical brochures
