  • Patent number: 9113274
    Abstract: A device for use in a hearing aid system comprising a radio antenna for reception and/or transmission to/from other devices in the hearing aid system is arranged to register a radio disturbance received by the radio antenna at an occasion when the radio antenna is not used for reception and/or transmission to/from the other devices. The device further relates to a transmission system comprising a mini receiver connected to a hearing aid device and comprising a radio antenna for reception of communications, a setting device comprising a radio antenna for communication of settings and audio information to the mini receiver, a transmitter device comprising a radio antenna for transmission of audio information to the mini receiver. At least one of the mini receiver, setting device, or transmitter device is arranged to register a radio disturbance at an occasion when its radio antenna is not used for reception and/or transmission.

  • Patent number: 8340331
    Abstract: A system for assisting a hearing impaired user is presented. The system includes a transmitter to transmit data representing audio intended to be heard by a hearing impaired person, the transmitter paired with at least one intended receiver. The transmitter includes: an analogue-to-digital converter to convert an analogue audio signal into digitally represented audio data, and a transmitter to transmit the digitally represented audio data in a radio signal on an active channel selected from a plurality of channels. The system also includes a receiver to receive data representing audio to be heard by the hearing impaired person, the receiver paired with the transmitter device. The receiver includes a receiver to receive the radio signal containing the digitally represented audio data, the radio signal being received from the transmitter on the active channel, and a digital-to-analogue converter to convert the digitally represented audio data into an analogue audio signal.
