Abstract: A method operates a hearing device in an audio presentation system. In this case, the hearing device has a wideband transmitter and a narrowband receiver. The audio presentation system has a plurality of audio transmitters that operate using narrowband transmission and are arranged so as to be spatially at a distance from one another in the intended usage state, and a plurality of wideband transmitters that are arranged so as to be spatially at a distance from one another in the intended usage state. A variable that is characteristic of a position of a hearing device relative to the audio transmitters is initially ascertained by the wideband transmitters of the hearing device and of the audio presentation system. A specific one of the multiple audio transmitters of the audio presentation system is then selected to transmit audio to the hearing device on the basis of this characteristic variable.

Abstract: An admission control method for a restricted-admission area uses a hearing apparatus having an ultra-wideband communication device. An area-affiliated narrowband communication device checks for presence of the hearing apparatus, which likewise has a narrowband communication device. Upon detecting the hearing apparatus, an ultra-wideband communication connection between an area-affiliated ultra-wideband communication device and the hearing-apparatus-affiliated ultra-wideband communication device is established. An admission authorization associated with the hearing apparatus is checked for and the ultra-wideband communication connection is a basis for ascertaining a distance of the hearing apparatus from the restricted-admission area. If the admission authorization of the hearing apparatus exists and the hearing apparatus is disposed within a predefined distance from the restricted-admission area, the admission restriction is at least temporarily lifted.

Abstract: A method for operating a smart mobile device. The method includes checking for or ascertaining the presence of a device known to the mobile device by way of a radio module in a locked state of the mobile device, in which manual access to the data content thereof is disabled. In the event that the presence of the known device is detected, an ultra-wideband radio connection is used to ascertain whether the known device is within a predefined distance from the mobile device. The locked state of the mobile device is canceled if the known device is within the predefined distance.

Abstract: Each of a hearing device and a mobile terminal of a hearing device system has a wideband communications apparatus, a narrowband communications apparatus, and a controller. The mobile terminal further has a position detection system. The controllers establish and maintain a narrowband connection between the hearing device and the mobile terminal during normal operation. When the narrowband connection is disconnected, the mobile terminal determines and stores its current position as a loss position of the hearing device using the position detection system. The stored loss position is displayed to a user in a search mode and a wideband connection is established via the wideband communications apparatus. The actual position of the hearing device is derived and output to the user based of the wideband connection. A charger of the hearing device may be found in the same way as the hearing device.
