Abstract: A hearing device includes a digital signal processing unit, a first electrical component, in particular a loudspeaker, and a second electrical component, in particular a microphone. The first electrical component is driven by the signal processing unit by way of two electrical line wires or interference source lines, and the second electrical component is connected to an electrical connecting line or receiver line. Each interference source line transmits a respective digital control signal during operation. To reduce or prevent coupling of interference effects to a signal transmitted via the receiver line, the two control signals fed into the interference source lines by the signal processing unit are modulated so a difference signal pertaining to the two control signals applied to the first electrical component is formed as a bipolar control signal alternating between precisely two voltage values, and a common mode signal formed from the two control signals is constant.
