Résumé

The effectiveness of a control system on a directional dipole noise source was discussed. It was found that a primary source with a non-cylindrical radiation directivity affected the performance of the control system. The analysis showed that the control system worked more effectively when it was used to create quiet zones in the area with the strongest primary-radiation directivity.
