abstract = "Active control systems were proposed in previous work for the three-dimension scattered radiation, where all the relevant simulations and experiments were implemented in three-dimensional free sound field. While for practical applications, the sound field conditions are usually complex,
such as with reflected surfaces. It should be answered whether the previous control system is still effective in this condition, and furthermore what improvements should be operated to ensure the control effect. In the present research, based on the mirror image principle, a modified methods
for calculating the control source strengths are proposed for the scattered radiation control in the sound field with a reflected surface, and the corresponding numerical simulations are implemented to detect the control effect. It is seen that the local active control is still effective with
the improved methods of the scattered radiation control.",
