Synergetic use of expertise - Fraunhofer IDMT draws on many years of expertise and thus generates value for I4.0

Synergetic use of expertise - Fraunhofer IDMT draws on many years of expertise and thus generates value for I4.0

Fraunhofer IDMT relies on a strong network of competence and partners from the fields of education, science and industry to implement projects. In order to realize their existing competencies in industrial applications, the scientists of the IMA business unit are always looking for new use-cases for acoustic condition monitoring or quality control.

Intelligent acoustic measurement technology

  • Sound recording (structure-borne sound and airborne sound measurements in disturbance-free and disturbed environments)
  • Customer-specific HW/SW development of multi-microphone arrays including data pre-processing and data transmission
  • Networking of sensors and time-synchronous transmission technology

Signal analysis and processing

  • Integrity and authenticity of (media) data and metadata
  • Confidentiality of (media) data and metadata
  • Legally compliant data management
  • Data security-friendly data analysis and thus data sovereignty
