LOW-LATENCY STREAMING FOR CROS AND BICROS
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.

Systems and methods for frequency-specific localization and speech comprehension enhancement
An exemplary spatial enhancement system performs frequency-specific localization and speech comprehension enhancement. Specifically, the system receives an audio signal presented to a recipient of a hearing device, and generates, based on the audio signal, a first frequency signal and a second frequency signal. The first frequency signal includes a portion of the audio signal associated with a first frequency range, and the second frequency signal includes a portion of the audio signal associated with a second frequency range. Based on the first and second frequency signals, the system generates an output frequency signal that is associated with the first and second frequency ranges and that is configured for use by the hearing device in stimulating aural perception by the recipient. This generating of the output frequency signal includes processing the first frequency signal to apply a localization enhancement and processing the second frequency signal to apply a speech comprehension enhancement.
