The invention discloses a semi-active noise control system and an aircraft. A semi-active noise control system includes a layer configured as part of an aircraft interior panel. The layer includes a plurality of conductive rails, a driver arrangement, a plurality of tuned mass dampers, and a plurality of sensors. Each of the plurality of tuned mass dampers includes an eigenfrequency dependent on a control signal applied to the tuned mass damper and is connected to the driver arrangement via at least one of the plurality of conductive rails and configured to receive the control signal from the driver arrangement. Each of the plurality of sensors is connected to the driver arrangement via at least one of the plurality of conductive rails and is configured to sense vibrations and/or acoustic sounds and to send measurement signals to the driver arrangement. The driver arrangement is configured to analyze the measurement signal, generate a control signal and send the control signal to the tuned mass damper such that the eigenfrequency of the tuned mass damper matches the frequency of the vibration and/or acoustic sound sensed by the sensor.
