Abstract: The disclosed technology generally relates to a microphone device configured to receive sound from different beams, where each beam has a different spatial orientation and is configured to receive sound from different directions. The microphone device is also configured to process the received sound using a generic or specific head related transfer function (HRTF) to generate processed audio and transmit the processed audio to hearing devices worn by a hearing-impaired user. Additionally, the microphone device can use a reference line and/or reference point when processing the received audio.

Abstract: A communication device, including a wireless interface including a transceiver unit, and a controller configured to control the transceiver unit when applying a first protocol which is a Bluetooth Low Energy protocol and a second protocol which is suitable for exchanging both audio data and non-audio data. The controller is further configured to apply a first control configuration while the transceiver unit is not used for audio data reception and/or transmission of audio data via the second protocol, and to apply a second control configuration while the transceiver unit is used for audio data reception and/or transmission of audio data via the second protocol. In the second control configuration duration of BLE connection events is limited to a maximum duration shorter than the maximum duration of BLE connection events in the first control configuration.

Abstract: A communication system maintains a signal processing license within a memory of the communication system. The signal processing license allows the communication system to perform a license-enabled signal processing function on signals received from one or more devices external to the communication system while the signal processing license is maintained within the memory. As such, the communication system detects that an additional communication system is within a transfer range of the communication system, and, in response, performs a transfer operation in which the signal processing license is transferred from the communication system to the additional communication system such that the signal processing license is no longer maintained within the memory once the transfer operation is completely performed.
