Abstract: An audio system such as a hearing assistance system includes an audio source device wirelessly communicating with one or more audio sink (destination) devices. The audio source and sink devices each include a sample clock for processing audio signal that is digitized and wirelessly transmitted. The sample clock of each of the one or more audio sink devices is synchronized to the sample clock of the audio source device to prevent audio sample over-runs or under-runs causing undesirable audio artifacts. In one embodiment, because audio packets may be lost in transmission, packet loss concealment techniques are used to improve audio reproduction. In one embodiment, link layer information is used for audio phase lock loop jitter reduction in the audio system.

Abstract: Methods and systems are described for transferring programming information to a hearing instrument. Such programming information may include hearing loss compensation parameters and/or other information pertaining to device operation. In one embodiment, each of a pair of hearing instruments prescribed and configured for a particular hearing loss contains the necessary information for operation on either the left or right ear.

In other embodiments, programming information is transferred wirelessly by an external device connected to a database.

Abstract: Disclosed herein, among other things, are methods and apparatus for providing a time-stamp based controller for synchronization of sink or source sampling rate with external packet rate. A method for wireless communications includes receiving a transmission of a packet using a wireless transceiver of an electronic device, and using a processor of the electronic device to read a first value of a system timer and store the first value as an arrival time-stamp. The packet is decoded and processed by the processor, and sent to an output. When the processed packet is sent, a second value of the system timer is read, adjusted and stored as a departure time-stamp. The arrival time-stamp and the departure time-stamp are used to calculate an adjustment stimulus for a sample rate actuator of the electronic device. The sample rate actuator is configured to maintain synchronization of sampling rate with an external packet rate.

Abstract: The present subject matter includes a system for communications between a transmitter and a receiver. In various embodiments, the system uses a sleep interval to allow the receiver to go to sleep between wake up times to “sniff” for transmissions from the transmitter. The system adjusts the length of the preamble of the transmitted signal or a repetition of packets to allow the receiver to detect a transmitted signal based on drift in the clocks of the system. In various embodiments, a receive channel is changed if a signal is not received at a prior channel selection. In various embodiments, the transmission is determined by detection of an event. In various embodiments, the event is an ear-to-ear event. In various embodiments, the receiver and transmitter are in opposite hearing aids adapted to be worn by one wearer.
