Noise & Vibration Systems

With more than 20 years’ experience, Ultra is the market leader in active noise and vibration control for aerospace applications.

To date, our Active Noise & Vibration Systems have been adopted on the following Platforms:

  • Bombardier Q100, Q200, Q300 and Q400
  • Bombardier Challenger 604
  • Lockheed Martin C-130
  • Beech King Air 350
  • Saab 2000 and 340

System Features

  • Microphones and/or accelerometers “listen” to the noise and vibration in the aircraft cabin
  • A control unit interprets these signals and determines the required outputs from the systems’ actuators
  • Actuators (loudspeakers or vibration actuators) introduce noise and/or vibration that is in opposite phase to that being created by the engines or propellers
  • This noise interferes with the noise from the engine or propellers canceling it out

Benefits to the Operator

  • Easier crew communication/increased passenger comfort
  • Greater crew coordination
  • Reduced crew fatigue
  • Enhanced safety (mission and hearing)
