Active noise and vibration control

Suppression of unwanted noise by superimposing noise of the same amplitude



CTTM has wide experience and technical resources for:

  • determining the technical feasibility of an active control device
  • using simulations to evaluate potential gains, both objective (noise reduction) and subjective (perceived aspects)
  • constructing prototype assemblies (electronic control device, actuators, monitoring sensors, etc.)
  • defining the physical domain and limitations of the device
  • drawing up requirements for the industrialization of systems
