Testing services for sound insulation and component vibrations

We advise you on acoustic issues in buildings, prepare expert reports and perform tests and calculations.

The requirements for old and new buildings have become increasingly stringent in recent years. Planners and contractors need to have a broad specialist knowledge of sound insulation to achieve a high level of home comfort.

Range of services

We offer the following services:

Sound and vibration measurement

  • Measurement and assessment of sound insulation and flanking transmission for components on the lightweight test rig in collaboration with EMPA in Dübendorf
  • Measurement and assessment of sound insulation in buildings: airborne and footfall sound insulation
  • Locating of sound bridges
  • Measurement and assessment of the vibration characteristics of components

Consultancy and expert appraisals

  • Appraisal of construction defects
  • Consultation on acoustic refurbishment of buildings
  • Optimisation of parts and components with regard to noise insulation and vibration susceptibility

Calculations

  •  Prognosis of sound insulation in buildings

All orders are carried out by qualified specialists from the relevant field and treated confidentially.

Infrastructure

We provide services and carry out development tasks using state-of-the-art laboratory equipment that includes the following:

  • Lightweight test rig (BFH-AHB and EMPA, Dübendorf)
  • Noise measurement set for performing building acoustics measurements (airborne and impact sound)
  • Sound intensity measurements
  • Vibration measuring kit for vibration analyses
  • Blower-door measuring devices for measuring the air-tightness of buildings, leak detection and joint permeability of building components
  • Thermal imaging camera
  • Wood moisture and climate data logger
  • Climate chambers and multiple climate chambers to investigate heat and moisture insulation of building components
  • 2D and 3D thermal-bridge calculations
  • WUFI® (transient heat and moisture software from the Fraunhofer Institute for Building Physics) to calculate heat and moisture flows
  • U-value measurement of components with a guarded hot box
  • Measurement of the thermal conductivity of building materials with a guarded plate measuring device
