    Noise emissions, noise evaluations, speech intelligibility, etc.

    We can provide the assistance you need to address your acoustic and vibration concerns:
    For people and the environment

    • Guideline and limit values for immissions and emissions protection
    • Legal aspects
    • Noise and vibration effects, psychoacoustics
    • Noise and vibration assessment at areas of work
    • Perceptibility of acoustic warning signals
    • Interior acoustic noise/privacy
    • Speech intelligibility

    For vehicles

    • Noise emissions of vehicles (rolling noise, powertrain noise, noise from auxiliary equipment, aerodynamic noise, curve and brake squeaking)
    • Acoustic properties of vehicle components (e.g. wheels, brake shoes, fans, environmental control systems)
    • Vehicle-side vibration influences
    • Noise and vibration-reducing measures for the vehicle
    • Acoustic signalling equipment
    • Interior acoustics and interior vehicle sound propagation (passenger area and driver's cab)

    For infrastructure

    • Noise and vibration emissions along rail transit routes
    • Acoustic quality of the rail running surface and acoustic properties of the permanent way (e.g. rail pads, ties)
    • Infrastructure-side noise-reducing measures (e.g. specially monitored track, sound barriers, rail web dampers)
    • Infrastructure-side vibration-reducing measures (e.g. mass-spring systems, sub-ballast mats, highly elastic rail fastening devices)
    • Noise and vibration emissions of bridges
    • General traffic noise, noise mapping
    • Noise in expansive areas (e.g. marshalling yards, transshipment stations, holding sidings)
    • Acoustic properties of infrastructure components (e.g. retarders)
    • Micro-pressure waves, acoustic warning signals, construction noise and construction-related vibrations

    Our equipment

    Test laboratory: If required, we will make use of our test laboratories to address your specific concerns, such as the test laboratory for acoustics and vibrations in Munich.
