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 (L) 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 (L), 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 (L) 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 (L) 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 (L), 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 (L) 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. <EOS>
