Acoustics

Description of the research group:

The acoustics working group has been dealing with acoustics in teaching and research for over 30 years. Mainly metrological processes and techniques in the air, body and ultrasound areas for the acquisition and analysis of noises on devices, machines, vehicles and buildings have been and are processed.

Typical examples:

  • Noise immission in factory buildings
  • Ultrasonic and force measurement sensors for early damage detection and process monitoring during punching, forging and drawing
  • Noise vibration processes on machines, conveyor and crane systems
  • Noise pollution and noise reduction in the household appliance industry
  • Sound pressure and sound power measurements on power tools
  • Sound intensity measurements on aircraft
  • Sound engineering for product optimization of machines, devices and vehicles
  • Active noise reduction (ANC) in vehicles and headphones

In addition, essential basics for sound intensity measurement are created at the institute and appropriate measuring devices are developed for this purpose. Another focus that the IMR has been pursuing for some time is the combination of control technology and acoustic measurement technology. Active noise compensation in the interior of motor vehicles is an example. With the help of suitable sound generators, the sound field generated by undesired noise sources is actively influenced in a targeted manner and certain sound images or noise patterns are approximated as best as possible. This technology was recently investigated at the institute as part of a cooperation with the Sennheiser company, also in connection with communication headsets and in-ear headphones.
