Apparatus and method for reducing noise for moveable target

A method for providing reduction of a noise level around a moveable target comprising:

• detecting a first location of the target;
• detecting a noise acoustic wave at the first location;
• providing a noise cancellation wave in response to the noise acoustic wave to a first space at and around the first location of the target, wherein the noise cancellation wave interferes with the noise acoustic wave;
• detecting a movement of the target;
• and
• providing a noise cancellation wave in response to the noise acoustic wave to a second space to cover the moving target, wherein the second space is larger than the first space.

A noise control system for controlling a noise level around a moveable target, comprising:

• a detecting system configured to detect a location and movement of the target;
• and
• a noise cancellation system including:
• a sensor for dynamically sensing a noise acoustic wave at the location of the target;
• signal processing circuitry connected to the sensor;
• and
• an acoustic signal generator connected to the signal processing circuitry,
• wherein said signal processing circuitry is configured to be responsive to a detection of the location of the target by the detecting system and the noise acoustic wave sensed by the sensor to control the acoustic signal generator to provide a noise cancellation wave to a first space at and around the location of the target, and
• wherein the signal processing circuitry is further configured to be responsive to a detection of the movement of the target by the detecting system and the noise acoustic wave sensed by the sensor to control the acoustic signal generator to provide a noise cancellation wave to a second space to cover the moving target, wherein the second space is larger than the first space.
