One embodiment attached to a vehicle suspension strut or vehicle suspension shock-spring assembly or a vehicle shock absorber includes a set of cylinders containing a number of magnets and a second set of cylinders containing a number of electrically conducting coils. The current acoustic level is compared to a desired level, and various cues are displayed to operators regarding corrective actions that can be taken to reduce or maintain the acoustic level at the desired level. Transparent electrodes are formed on the shielding mask, and display electrodes are formed on the transparent electrodes.
