Acoustics and vibrations

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.
