Abstract (en)
The device (1) has an actuator (3) arranged on a carrier plate (2) that is excited by vibrations. The plate is connected with an acoustic insulating material (9). Noise signals of the actuator are regulated by a control/regulation device (4) that is connected with the actuator. An amplifier (5) is arranged between the device (1) and the actuator. The plate is formed as a wall plate, ceiling plate, floor plate, room divider, furniture plate, cabinet plate and/or partition wall. A memory of a computer of the device (4) stores noise tone-characteristics that are changeable by a preset program. The insulating material is selected from mineral wool, gypsum foam, aluminum foam, polyurethane foam, melamine resin foam, hemp wool, non-woven fabric and/or felt material.
