• What does footfall sound look like?

Wölfel is an approved noise control test facility and performs all necessary noise measurements

  • How can I make sure that my children, when they are scurrying around, do not annoy the new tenant?
  • How loud is it when I'm living next to the elevator?
  • Where exactly does the noise of the air-handling system go to?

    We handle all issues in the field of building acoustics – noise inside or outside of buildings, structure-borne noise or airborne noise or sound-absorbing measures at workplaces

    The architectural-acoustics-related properties of partition walls and floor slabs have a significant influence on the quality and usability of buildings. We are ready to share our knowledge with you to answer any questions you might have about architectural acoustics. We are a noise abatement testing laboratory recognized by the VMPA (Verband der Materialprüfungsanstalten, Association of Material Testing Laboratories) and carry out air and footfall sound measurements. We support you not only when you take measurements in existing buildings but also accompany you through the planning and completion phases of building restoration and new building projects.

    Our services in the field of architectural acoustics

    Effective impact sound insulation
    Effective impact sound insulation
    • Development of measures to provide protection against outside noise and protection against noise inside buildings
    • Measurements of the transmission of footfall sound and air-borne noise:
      • Short-time measurements according to DIN EN ISO 10052
      • Quality tests according to DIN EN ISO 16283 parts 1 to 3
    • Development of measures to provide protection against noise generated by building equipment, such as heating, ventilation, air-conditioning and water supply systems or elevators
    • Determination of sound insulation and noise abatement measures
    • Measurement of sound absorption coefficient, specific wall impedance and reflection factor according to DIN EN ISO 10534-2

    In addition, we also deal with occupational safety and health, particularly with regard to noise abatement at workplaces. The latter involves noise reduction in workrooms by taking measures at the source, setting up noise barriers and designing interior structures for sound absorption purposes. The field of occupational safety and health also includes the propagation of sound in workrooms. Determining sound decay curves by calculation and measurement based on VDI 3760 is an appropriate method to check whether the sound-engineering requirements in terms of occupational safety and health in factory workrooms are met and if yes to which extent.
