Abstract
A system for reducing far-field noise produced by well operations includes a passive sound barrier shielding an area, in which the well operations are performed, in an open-air environment. The system further includes a sound sensor to receive near-field noise from the well operations. The system further includes an analysis module, coupled to the sound sensor, to generate an anti-noise signal. The system further includes active anti-noise generators, coupled to the analysis module, to generate anti-noise, based on the anti-noise signal, that destructively interferes with noise from the well operations outside of the passive sound barrier at a predetermined distance from the passive sound barrier. The analysis module generates the anti-noise signal based on the near-field noise, the predetermined distance, and adjustable positions and orientations of the active anti-noise generators.
