Abstract
A system for controlling noise in a fenestration assembly (e.g., a window) includes a fenestration assembly with at least one glazing and a frame. The at least one glazing has a surface. At least one sensor is coupled to the at least one glazing and is configured to generate noise detection signals. An actuator is positioned on the surface of the at least one glazing and has a plurality of regions. A controller is coupled to the sensor and the actuator and is configured to control each of the regions of the actuator to generate a different frequency based on the noise detection signals. Alternatively, each of the regions may be controlled to generate a frequency with a different phase shift based on the noise detection signals.
