Noise control system, active noise cancellation

Active noise cancellation noise control system

Encore is the first application of this dynamic new noise cancellation technology by Buick®. Here's how it works:

  • Ceiling-mounted microphones detect engine noise
  • The frequencies of this noise are processed by the system's computer
  • Counteracting sound waves are directed through the audio system’s speakers and subwoofer, in effect canceling out the noise
  • Active noise cancellation is an integral part of Buick QuietTuning technology, which is one way in which Encore has achieved impressive sound benchmarks for refinement
