The Siemens VCO1S Silent for Active Noise Cancellation (ANC) solution utilizes sensors, microphones, speakers and advanced audio processing to sense and diminish unwanted noise in the vehicle cabin. Transient, steady-state, tonal and broadband cabin noise coming from the engine, transmission and road is reduced by the system without interfering with the desired music, navigation system audio or even emergency vehicle sirens. A unique active cancellation method offers high-performance advantages without the weight penalty found in passive legacy methods. Flexible integration, easy configuration and tuning capabilities mean that the Siemens VCO1S Silent solution is well suited to cover a broad range of automotive applications.
VCO1S Silent - Engine Order Cancellation (EOC)
Effective and easily adaptable engine noise reduction
- Reduces narrow-band periodic and harmonic engine noise (engine orders)
- Uses engine speed (tachometer) to synthesize noise reference signals
- Adaptively adjusts reference filters to compensate for targeted engine orders
- No interference with in-cabin audio quality
VCO1S Silent Road Noise Cancellation (RNC)
Effective and easily adaptable road noise reduction
- Reduces structure-born broadband and impulsive noise
- Uses accelerometers for noise reference signals
- Accelerometers can detect road noise and engine noise
- Adaptively adjusts reference filters to compensate for detected noise
