Title
(EN) ACTIVE NOISE CONTROL FOR HYDRAULIC FRACTURING EQUIPMENT
(FR) COMMANDE DE BRUIT ACTIVE POUR ÉQUIPEMENT DE FRACTURATION HYDRAULIQUE
Abstract
(EN)
A method for noise attenuation includes comparing a frequency of noise generated by a plurality of noise sources with a plurality of frequencies associated with a pre-determined noise spectrum and stored in a computer system, identifying one or more noise sources that generate the noise based on the comparison of the frequency of the noise and the plurality of frequencies stored in the computer system; generating anti-noise corresponding to the noise; and outputting the anti-noise using one or more noise mitigation devices associated with the one or more noise sources.
(FR)
L’invention concerne un procédé d'atténuation de bruit consistant à : comparer une fréquence de bruit générée par une pluralité de sources de bruit avec une pluralité de fréquences associées à un spectre de bruit prédéterminé et stockées dans un système informatique ; identifier une ou plusieurs sources de bruit qui génèrent le bruit d’après la comparaison de la fréquence du bruit et la pluralité de fréquences stockées dans le système informatique ; générer un anti-bruit correspondant au bruit ; et émettre l’anti-bruit à l'aide d'un ou de plusieurs dispositifs d'atténuation de bruit associés à la source ou aux sources de bruit.
