A method for controlling an operating parameter of an acoustic apparatus, the method comprising at least the following steps: - implementing a screen displaying at least one window including a cursor able to occupy a plurality of positions relative to a reference of the window, the cursor being movable relative to the window in a movement direction parallel to the screen, the positions of the cursor respectively representing a plurality of values of the operating parameter extending between a minimal value and a maximal value, - displaying the cursor in an initial position relative to the reference representative of an initial value of the operating parameter, - acquiring an elementary command from an operator, - moving the cursor with respect to the reference, as a function of the acquired elementary command, from the initial position to a final position in order to select a final value of the operating parameter in a range of selected values containing the initial value, and - sending of the selected final value to the acoustic apparatus, the range of selectable values having an amplitude strictly less than the difference between the maximum value and the minimum value, characterized in that: - the acquisition of the elementary command comprises a sub-step for the movement of a pointer by the operator in the window, the movement of the cursor being done as a function of the movement of the pointer, and - in the sub-step for movement of a pointer, a speed parameter of the pointer is obtained, the speed parameter being representative of a speed of the pointer projected over the movement direction, the movement of the cursor comprising at least a first phase in which the cursor is moved relative to the reference of the window in the movement direction at a speed substantially equal to the speed parameter of the pointer if the speed parameter is above a predetermined threshold, or at a speed strictly lower than the speed parameter if the speed parameter is less than or equal to the predetermined threshold. - implementing a screen displaying at least one window including a cursor able to occupy a plurality of positions relative to a reference of the window, the cursor being movable relative to the window in a movement direction parallel to the screen, the positions of the cursor respectively representing a plurality of values of the operating parameter extending between a minimal value and a maximal value, - displaying the cursor in an initial position relative to the reference representative of an initial value of the operating parameter, - acquiring an elementary command from an operator, - moving the cursor with respect to the reference, as a function of the acquired elementary command, from the initial position to a final position in order to select a final value of the operating parameter in a range of selected values containing the initial value, and - sending of the selected final value to the acoustic apparatus, - the acquisition of the elementary command comprises a sub-step for the movement of a pointer by the operator in the window, the movement of the cursor being done as a function of the movement of the pointer, and - in the sub-step for movement of a pointer, a speed parameter of the pointer is obtained, the speed parameter being representative of a speed of the pointer projected over the movement direction, the movement of the cursor comprising at least a first phase in which the cursor is moved relative to the reference of the window in the movement direction at a speed substantially equal to the speed parameter of the pointer if the speed parameter is above a predetermined threshold, or at a speed strictly lower than the speed parameter if the speed parameter is less than or equal to the predetermined threshold.
