can be corrected more simply are known in some embodiments the actuator 3 is connected to an audio amplifier 5 that receives its audio signals such as for example noise signals from a control or regulating device 4 this control device may have for example a storage medium 10 which may be a cd player for example in some embodiments the system is adaptively designed and depending on the difference of the insulating material 9 applied to the vibrating panel 2 emits different noise signals taking into account the acoustic damping of the panel in order to be able to emit in each case an identical noise signal with identical character in some embodiments different noise signals may be locally switchable at the vibrating panel 2 for example via suitable switches 4 a the same sound characteristic being producible or for all embodiments the same subjective sound sensation being perceptible always taking into account and correcting the acoustic damping properties of the material 9 applied to the panel 2 the amplitude of the acoustic signals is also adjustable via the switches 4 a furthermore the control device 4 is connected for example via a stationary usb connection 8 to a computing unit or a data base 6 via which the control unit 4 and or the amplifier 5 can be controlled likewise it is possible for acoustic signals such as for example noise signals which can be stored in the computing unit or the data base 6 to be fed into the control device 4 in some embodiments the control device 4 is a.
