Fields of Application

  • Vibration analysis of engines/gear units
  • Noise radiation analysis Development of engines/gear units
  • Engine development - combustion/emissions/noise
  • Identification and analysis of noise sources (intensity measurements / acoustic holography)
  • Optimisation of engine structures (using Laser Scanning Vibrometer)
  • Analysis of correlations between engine combustion behaviour (Indimaster) and air-borne noise
