    Abstract: Embodiments include systems with active sound canceling properties, fenestration units with active sound canceling properties, retrofit units with active sound canceling properties and related methods. In an embodiment a system can include a sound cancellation device include a sensing element to detect vibration of a transparent pane and/or a sound input device configured to detect sound incident on the transparent pane, as well as a vibration generator configured to vibrate the transparent pane and a sound cancellation control module. The sound cancellation control module can evaluate the detected vibration of the transparent pane at two or more discrete frequency bands. The sound cancellation control module can cause the vibration generator to vibrate the transparent pane causing destructive interference with sound waves at the two or more discrete frequency bands. Other embodiments are also included herein.

    Abstract: Embodiments include fenestration units with active sound canceling properties, retrofit units with active sound canceling properties and related methods. In an embodiment a fenestration unit with active sound canceling properties can include an glazing unit including an exterior transparent pane, an interior transparent pane, and an internal space disposed between the exterior and interior transparent panes. The fenestration unit can include an active noise cancellation system including an exterior module including a sound input device and a signal emitter. An interior module can include a signal receiver to receive the signal from the signal emitter, and a vibration generator configured to vibrate the interior transparent pane. A sound cancellation control module can control the vibration generator to vibrate the interior transparent pane and generate pressure waves causing destructive interference with a portion of the sound waves received by the sound input device. Other embodiments are also included herein.
