Abstract
A power-saving control of the receiver in hearing devices with wireless transmission to other devices is also to be possible without significant interferences. Provision is thus made in accordance with the invention for a hearing apparatus, in particular a hearing device, with a transmission facility for wireless data transmission in a main frequency band, a loudspeaker and a control facility for controlling the loudspeaker with a control signal, with the frequency spectrum of the control signal having a significant notch in the range of the main frequency band. A “noise-shaping” of this type can be achieved by pulse-density modulated receiver control signals.
