Abstract[English]
A method and system for noise cancellation is disclosed. In one embodiment, the method may include receiving, from a first sensor, a first signal indicative of a noise generated by an equipment. The first sensor may be configured to generate the first signal indicative of the noise generated by the equipment. The first sensor may be positioned in proximity to the equipment. The method may further include generating a noise cancellation signal based on the first signal and triggering a speaker to generate a sound corresponding to the noise cancellation signal, wherein the speaker is positioned in proximity to the equipment.[French]
L'invention divulgue un procédé et un système d'annulation de bruit. Dans un mode de réalisation, le procédé peut consister à recevoir, en provenance d'un premier capteur, un premier signal indiquant un bruit généré par un équipement. Le premier capteur peut être conçu pour générer le premier signal indiquant le bruit généré par l'équipement. Le premier capteur peut être positionné à proximité de l'équipement. Le procédé peut en outre consister à générer un signal d'annulation de bruit sur la base du premier signal et à déclencher un haut-parleur pour générer un son correspondant au signal d'annulation de bruit, le haut-parleur étant positionné à proximité de l'équipement.
