An active noise cancellation system () for cancelling environment noise perceived by a driver or passenger seated in a seat () mounted in a cabin of a vehicle, in combination with said seat, the seat comprising a seat cushion (), a seat back () coupled to the seat cushion at a bottom end and extending upwards to a seat shoulder (), and a headrest () coupled to the seat back, extending upwardly from the seat shoulder, the active noise cancellation system comprising an active noise cancellation circuit (ANC) (), a plurality of microphones () mounted in the headrest and connected electrically to the ANC, and a plurality of speakers () mounted in the seat and connected electrically to the ANC circuit. The plurality of microphones comprises at least one first microphone mounted on a right side of the headrest and at least one second microphone mounted on a left side of the headrest, and the plurality of speakers comprises at least one first speaker mounted in the seat shoulder on a left side and at least one second speaker mounted in the seat shoulder on a right side, the right speaker configured to generate a noise cancellation sound from a noise signal picked up by the right microphone processed by the ANC circuit and the left speaker configured to generate a noise cancellation sound from a noise signal picked up by the left microphone processed by the ANC circuit.

In-seat active noise cancellation system for moving vehicles

An active noise cancellation system comprising an active noise cancellation circuit connected to a microphone arranged to sense environmental noise, the active noise cancellation circuit comprising: &#x2014;an analog-to-digital converter (ADC) arranged to convert the sensed environmental noise to a digital environmental noise signal, &#x2014;a prediction filter configured for predicting a plurality D of inverted digital environmental noise samples and generating a digital inverted environmental noise signal, &#x2014;a digital-to-analog converter (DAC) to convert the digital inverted environmental noise signal to an analog inverted environmental noise signal for cancelling the environmental noise.
