When the "J's" are working hard they are adding some bite to the pad. This extra bite is felt and heard as slight groaning or low-frequency humming.
For typical around-town driving, many don't notice any difference at all. Only when braking heavily will they remind you that they are helping slow the car down with added effectiveness. Smooth or plain-faced rotors don't generate this noise, but they don't generate the same braking power either!
