VCO1S Silent

Superior noise control and cancellation performance diminish unwanted road and engine noise in passenger quiet zones without interfering with desired audio or ESS (Engine Sound Synthesis) performance.

The Siemens VCO1S Silent ANC employs microphones, speakers, and advanced audio processing to sense and diminish unwanted noise in the vehicle cabin. Quiet zones created around the driver and passengers throughout the steady-state, dynamic, and non-periodic components of engine, transmission, and road noise without interfering with the desired music, the audio of navigation systems, or the sirens of emergency vehicles.

The performance advantage of Siemens VCO1S Silent ANC solution delivers these functions with fewer hardware components. The resulting system requires less tuning and calibration than competing solutions. Flexible tuning makes Siemens solution well suited to cover a broad range of automotive trim levels.

VCO1S Silent details:

Siemens VCO1S Silent ANC has several algorithms that are designed to limit the adaptive filter’s ability to amplify reference signals. These are exposed as tuning parameters and prevent the algorithm from runaway computations. The more aggressive the stability control settings, the less the noise cancelation. Thus, balancing performance and stability are an important part of tuning.

Benefits:

  • Effective and cost-efficient noise reduction
    • Proven, easy-to-install system for both OEM and after-market parties
  • Ideal for both entry-level and luxury applications
