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 one way in which Encore has achieved impressive sound benchmarks for refinement.
