  • the channel of the right channel is played on the listener.
  • the hearing aid supplying the left ear the left channel is correspondingly played on the listener in the case of stereophonic audio data.
  • the invention recognizes that unnecessarily energy is consumed with such a technique in the transmission of particular stereophonic audio data in the listening device, because in each of the two hearing aids, the complete stereophonic audio signal is received and processed, although for output via the respective Only the right or left channel of the audio signal is needed.
  • the invention is based on the consideration that the energy requirement for recording stereophonic audio data in a binaural hearing device can be reduced if the data transmission between the two hearing devices implemented in modern binaural hearing aids is also intelligently utilized by inductive coupling for the transmission of audio data ,
  • the invention proposes in a third step to actively switch only one of the two hearing aids for receiving and further processing audio data (active audio reception state), while the other of the two hearing aids for receiving and further processing stereophonic audio data is deactivated (deactivated audio reception state).
  • active audio reception state active audio reception state
  • deactivated audio reception state deactivated audio reception state
  • the hearing aid which is in the deaf audio receiving state, receives audio data on the inductive coupling established connection from the other hearing aid, which is in the active audio receiving state.

  • the methods of coding stereophonic audio data by channel coupling are those methods that take into account the given redundancy in the two stereo channels.
  • the amount of data to be transmitted for stereo signals can be reduced by transmitting the stereophonic audio data in the form of a DC and a differential signal; the stereo channels are more consistent than they are different.
