1. A structural damper comprising:
an acoustic black hole;
at least one sensor;
a damper structure;
an actuator configured to apply an actuating force to the damper structure at a different location to the acoustic black hole; and
a controller configured to control the actuator in dependence on a signal from the at least one sensor so as to provide structural damping of a primary structure.
