9 . The hearing device of claim 1 , wherein:
the hearing device is communicatively coupled to a portable communication device having a display; and
the portable communication device is configured to display video received from the streaming source that corresponds to content of the hearing-impaired audio stream.
10 . The hearing device of claim 1 , wherein:
the hearing device is communicatively coupled to a portable communication device having a display via a neck loop receiver and an inductive link; and
the portable communication device is configured to display closed captioning data or video received from the streaming source that corresponds to content of the hearing-impaired audio stream.
11 . The hearing device of claim 1 , wherein:
the audio streaming circuit is configured to establish wireless connectivity with the streaming source via a first communication link; and
the configuration circuit is configured to receive configuration parameters comprising a predetermined stream identifier via a second communication link different from the first communication link for configuring the hearing device to receive the hearing-impaired audio stream from the streaming source.
12 . The hearing device of claim 11 , wherein:
the first communication link comprises a long-range communication link configured to communicatively couple the streaming source and the hearing device; and
the second communication link comprises a short-range communication link configured to communicatively couple a source of the configuration parameters and the hearing device.
13 . The hearing device of claim 11 , wherein the configuration parameters are received from a beacon or a portable communication device.
14 . A method of communications for a hearing device configured for use by a wearer, comprising:
establishing wireless connectivity between a multicast electromagnetic audio streaming source and the hearing device;
selecting, by the hearing device, a hearing-impaired audio stream from a plurality of electromagnetic audio streams broadcasted by the streaming source;
configuring the hearing device to enable reception of the hearing-impaired audio stream and to play the hearing-impaired audio stream to the wearer's ear; and
communicatively coupling the hearing device with a portable communication device having a display via a neck loop receiver and an inductive link; and
presenting, on the display, closed captioning data or video received from the streaming source that corresponds to content of the hearing-impaired audio stream.
15 . The method of claim 14 , comprising applying processing to the hearing-impaired audio stream to enhance intelligibility of speech content of the hearing-impaired audio stream.
16 . The method of claim 14 , comprising applying processing to the hearing-impaired audio stream to enhance listening comfort during playing of the hearing-impaired audio stream to the wearer's ear.
