NVH: Noise, Vibration and Harshness Control

Soucy Baron has developed expertise in analysis and control of noise, vibration and harshness (NVH). Applications in the NVH field are numerous; one example that benefits greatly from our science is the engine mount, since this component isolates the chassis from engine vibration. The company is well equipped to test parts directly on the customer application.

There are three main ways to improve NVH control:

  • Reducing the magnitude of the stress
    (e.g. improvement of the rotating mechanism)
  • Stopping the noise and vibration pathway (e.g. a barrier or an isolator)
  • Absorbing noise and vibration (e.g. noise absorbers or mass dampers)

Soucy Baron designs parts so as to reduce these disturbances by controlling elements such as specific rigidity zones on defined axes. In addition, the geometry and compounding of rubber parts are optimized to meet the specifications for the desired rigidity and load cases. In this case, the engineering team's challenge is to choose the optimal method to control noise and vibration.
