Abstract: An exemplary hearing device is configured to receive, from a source, sequential data packets each identified by a sequence number. The hearing device receives, from an additional hearing device configured to also receive the sequential data packets, a first particular sequence number indicating a last of the sequential data packets received without discontinuity by the additional hearing device. The hearing device selectively transmits, based on the first particular sequence number and to the additional hearing device, a data packet included in the sequential data packets received from the source, the data packet identified by a sequence number that is based on the first particular sequence number.

Abstract: An exemplary hearing device is configured to concurrently maintain a first link with a source and a second link with a second hearing device. The hearing device scans, while not receiving data via the first link, the second link for a preamble of a binaural data packet for a first time period. Based on whether the preamble is detected, the hearing device selectively: receives the binaural data packet and ignores the first link while receiving the binaural data packet if the preamble of the binaural data packet is detected during the first time period; and scans the first link for a preamble of a data packet for a second time period if the preamble of the binaural data packet is not detected during the first time period.

Abstract: An exemplary method comprises a first hearing device receiving a data packet transmitted from a source device; incrementing, in response to receiving the data packet, a first payload counter value; receiving a second payload counter value transmitted from a second hearing device; comparing the second payload counter value to the first payload counter value; and performing, based on the comparing, an action with respect to the first payload counter value.

Abstract: Systems, methods and software for sample rate conversion with unknown input and output clocks are disclosed. In one embodiment, a method for an asynchronous transfer of audio data includes: receiving the audio data by an antenna of a receiver (RX); storing the audio data in an input buffer of the RX; and receiving data words from the input buffer by a sample rate converter (SRC). The consecutive data words are received from the input buffer at an adjustable period T. The method further includes tracking a filling level of the input buffer; and based on the filling level of the input buffer, adjusting the adjustable period T. When the filling level of the input buffer is below the target level of the input buffer, the adjustable period T is increased. When the filling level of the input buffer is above the target level of the input buffer, the adjustable period T is decreased.

Abstract: An exemplary hearing device is configured to receive, from a source, a data packet, the data packet including a plurality of frames including a first frame and a second frame. The hearing device determines that the data packet has an invalid checksum. The hearing device accesses, in response to the determining that the data packet has the invalid checksum, a first frame checksum for the first frame and a second frame checksum for the second frame. The hearing device determines that the first frame checksum is invalid and that the second frame checksum is valid. The hearing device discards, based on the first frame checksum being invalid, the first frame and stores, based on the second frame checksum being valid, the second frame.

Abstract: Provided is a method for operating two hearing devices. The method includes establishing a first bi-directional wireless connection between a primary hearing device and a wireless communication device over a first wireless link, eavesdropping on the first wireless link, by a secondary hearing device, over a second wireless link between the wireless communication device and the secondary hearing device, and establishing a second bi-directional wireless connection between the primary hearing device and the secondary hearing device over a third wireless link. The method further includes monitoring the link quality of the first wireless link and/or the second wireless link, and assigning to either the secondary hearing device or the primary hearing device the role of transmitting audio-related packets towards the wireless communication device, based on the quality of at least one of the first wireless link or the second wireless link. An audio communication system is also provided.
