This report describes the active control systems for reducing floor impact noise. The systems are comprised of actively controlled modular panels of light weight, which wholly cover the surface of concrete slab structure in the ceiling, and in each of which the mechanical vibration is controlled independently with moving coil actuators. In this report, first, vibration control system is presented. Second, acoustic evaluation of active insulation panel is presented. In the latter evaluation lower performance was acknowledged than expected from the former measurement, which was inferred to be caused by less computing precision of micro-computer controller than PC controller.
