Noise, Vibration and Harshness NVH

Unwanted vibrations and noises cause problems and affect the life and comfort. They lead to the most common directly perceived quality characteristics of a product. Development accompanying can be controlled early with an airborne and structure-borne noise analysis. Understanding and recognizing where and how vibrations occur in the product is an essential aspect here.

  • Modalanalysis / Eigenfrequenzen
  • Modal response analysis
  • Random response analysis
  • Power Spectral density PSD
