A noise control system is provided for controlling a noise level around a
moveable target. The noise control system has a detecting system
configured to detect a location and movement of the target, and a noise
cancellation system. The noise cancellation system has a sensor for
dynamically sensing noise at the location of the target. The noise
cancellation system is configured to be responsive to detection of the
location of the target by the detecting system and the sensed noise to
provide a noise cancellation wave to a first space at and around the
location of the target. The noise cancellation system is further
configured to be responsive to detection of the movement of the target by
the detecting system and the sensed noise, and to provide a noise
cancellation wave to a second space to cover the moving target. The
second space is larger than the first space.
