Abstract:
Disclosed wireless systems, devices, and methods can leverage existing hardware for BLE communications to provide a low-latency streaming (LLS) link suitable for supporting CROS and BiCROS features in hearing aids. An illustrative embodiment of a low-latency audio streaming method includes: (a) sending intermittent packets of digital audio data as a wireless signal; and (b) for each intermittent packet: (A) listening for a responsive packet; and (B) sending the digital audio data in a retransmitted packet only if no responsive packet is detected. Any retransmitted packet that is sent follows the corresponding intermittent packet with a delay no greater than a length of two interframe spacing (IFS) intervals separated by a responsive packet. An illustrative embodiment of a low-latency audio streaming device includes a transmit chain and a receive chain. The transmit chain periodically transmits intermittent packets of digital audio data as a wireless signal. The receive chain operates to detect a responsive packet to each intermittent packet. The transmit chain retransmits a packet of digital audio data each time the receive chain fails to detect a responsive packet, ensuring a delay no greater than a length of two IFS intervals separated by a responsive packet.

Claim (Index 20):
The system of  claim 19 , wherein the responsive packets include digitized audio data from an input transducer in the second hearing aid, and wherein the first hearing aid includes an output transducer that produces an augmented audio signal based on the digital audio data from the microphone and the digitized audio data from the input transducer.
