Akustik Center Austria


Too much noise makes one sick, this fact is well known and scientifically confirmed. In order to increase sound insulation in buildings, we therefore test, research, and improve the sound insulation of constructive components in the Akustik Center Austria – the sound laboratory of Holzforschung Austria, of TGM (Technologisches Gewerbemuseum) and of Technical University Vienna. In addition to walls, ceilings, and roofs, also doors, windows and other components are examined and further developed in terms of building acoustics. Alongside the classical, accredited component tests, we also work on various research projects at a national and international level.

Measurements

In the Akustik Center Austria, we carry out building-acoustic examinations for the detection, research, and further development of the sound-insulation properties of components and component nodes. Classic sound pressure level measurements are used here as well as intensity probe measurements and vibration analyses using laser Doppler vibrometry.

The Akustik Center Austria specializes in the inspection of prefabricated components, which means that sound measurements can be carried out very economically. However, there is enough space in the test hall at ground level for on-site production and for converting the components.

Test stands

The M test stand is available in the Akustik Center Austria for "standard sound measurements" and larger measurement and test programmes. Walls and ceilings are installed outside of the test stand in the test frames provided. This reduces the test stand occupancy time and thus the costs incurred. By rapidly changing the test frames, e.g. up to four wall measurements per day are possible.

We use the XL test stand in the Akustik Center Austria for a detailed examination of the low-frequency component behaviour, for junction analysis, and for special measurements (e.g. impact sound insulation of a cantilevered balcony slab). This test stand, which is unique in the D-A-CH area, has a significantly larger test room volume than the M test stand and enables greater flexibility in test setups.

Our services


Air and impact sound measurements

Individual measurements as well as large-volume measurement series for determining the air and/or impact sound insulation of components such as walls, facades, ceilings, roofs, doors, windows, lift and slide elements, balconies etc.

Junction analyses

  • Determination of the flanking insulation of component nodes (T and cross joints)
  • Diagonal measurements etc. to determine differences in sound pressure level

Vibration analysis

Determination of the vibration behaviour of component surfaces

Examination of special structures

Laboratory examination of constructions that require more conversion and space, e.g. cantilevered balcony slabs or sewage pipes in an installation shaft

Available infrastructure:


  • Test hall accessible by vehicle with work surfaces for the conversion and on-site production of components
  • Test frames for time- and cost-saving preparation of the test specimens
  • Hall cranes 2 x 10 tons for loading the test frames e.g. with prefabricated components
  • M test stand for air and/or impact sound measurements (test room volume 54m³ – 60m³)
  • XL test stand for air and impact sound measurements, especially in the lower frequency range, flank sound tests and special measurements with increased conversion effort (test room volume 138m³ – 153m³)
  • Subwoofer for component tests in the lower frequency range
  • Automatic measuring system for sound field scanning in the XL test stand
  • Laser Doppler vibrometer for vibration analysis of surfaces
  • Intensity probe for sound intensity measurement on components
  • Measuring system for determining the dynamic stiffness of insulation materials
