Wireless streaming to hearing assistance devices

摘要

Disclosed in some examples are methods, systems, apparatus, and machine readable mediums which mitigate multipath fading and extend the robustness and the useable range of the wireless link between a streaming device and a hearing assistance device. In some examples, this may be accomplished by utilizing redundant wireless sources of the streaming data—that is, multiple copies of the streaming information may be sent to the hearing assistance devices. To prevent interference, at least one transmission parameter may be varied between the transmissions (e.g., frequency, channel, time, coding, or the like).

主权项

1. A method for receiving streaming audio with a first hearing assistance device from a system including a second hearing assistance device and a streaming audio transmission device, the method comprising:
at the first hearing assistance device:
receiving a packet of stereo streaming audio data from a streaming audio transmission device over a first wireless link;receiving a second packet of the stereo streaming audio data from a second hearing assistance device over a second wireless link, the second hearing assistance device receiving the packet of stereo streaming audio data from the streaming audio transmission device and retransmitting at least a portion of the stereo streaming audio data in the packet to the first hearing assistance device over the second wireless link as the second packet;determining a first quality metric for the first wireless link;determining a second quality metric for the second wireless link;selecting an output packet based upon the first and second quality metrics, the output packet comprising the first packet if the first quality metric is better than or equal to the second quality metric and the second packet if the second quality metric is better than the first quality metric; andoutputting to a speaker of the first hearing assistance device, audio corresponding to the output packet.
