Abstract: A system for communication between one or more remotely controllable devices and a hearing assistance device includes a gateway device. The hearing assistance device detects voice commands issued by its wearer. The gateway device wirelessly communicates with the hearing assistance device, produces one or more control signals based on the voice commands, and routes the one or more control signals to one or more devices selected from the one or more remotely controllable devices according to the voice command.

Abstract: A hearing assistance system including a hearing instrument designated as a master device and at least another hearing instrument designated as a slave device. The master device is communicatively coupled to the slave device via a wireless link. The master device has a master clock and generates master time stamps for specified events timed by the master clock. The master time stamps are sent to the slave device via the wireless link. The slave device has a slave clock and generates slave time stamps for specified events timed by the slave clock. The slave clock is adjusted for synchronization to the master clock using the master time stamps and the slave time stamps.

Abstract: Described is state switch for a hearing aid that provides an input to the hearing aid's processing circuitry indicating that battery power has been disconnected by a power switch. The state switch and power switch are configured to operate in parallel. The state switch may provide a signal to a GPIO (general purpose input-output) of the processing circuitry indicating that the battery has been disconnected. Immediately after the battery is disconnected, voltage is maintained for a brief period due to the capacitance of the circuitry, which enables the processing circuitry to take certain steps to avoid device misbehaviors.

Abstract: A hearing assistance device for use by a listener includes a microphone, a receiver, and a processing circuit including a plurality of functional modules to process the sounds received by the microphone for producing output sounds to be delivered to the listener using the receiver. The processing circuit detects one or more auditory conditions demanding one or more functional modules of the plurality of functional modules to each performed at a certain level, and dynamically allocates computational resources for the plurality of functional modules based on one or more auditory conditions.

Abstract: Embodiments of packet loss concealment for phone-to-hearing-aid streaming are generally described herein. A method for packet loss concealment can include receiving a first frame at a hearing assistance device, determining, at the hearing assistance device, that a second frame was not received within a predetermined time, and determining a first set of sequential samples that match the first frame. The method can include cross-fading the first frame and the first set of sequential samples to create a first cross-faded frame and extrapolating a third frame to replace the second frame using the first set of sequential samples and an autoregressive model.

Abstract: An audio system includes a transient suppression circuit that rectifies an input signal representing target sounds and transient sounds and produces a threshold envelope of the rectified input signal. The transient suppression circuit accumulates the difference between the rectified input signal and the threshold envelope, and normalizes the accumulated difference using the rectified input signal. A gain is calculated using this normalized accumulated difference and applied to the input signal to suppress the transient sounds without substantially affecting the target sounds.

Abstract: The present subject matter includes systems and methods for detecting a new hearing aid battery and estimating hearing aid battery life by analyzing changes in battery voltage signatures during the hearing aid device booting process. The analysis may include analyzing a boot signature voltage drop occurring upon initial application of a higher load. The analysis may include analyzing a boot signature voltage slope occurring during sustained application of a higher load. The analysis may also include analyzing a boot signature voltage droop occurring throughout application of a lower load and application of a higher load.

Abstract: Systems, devices, and methods are provided to inhibit apparent amplitude modulation in non-linear processing that causes distortion in a processed signal. One aspect of the invention includes a hearing aid. The hearing aid includes a microphone to receive an input signal, a speaker to reproduce the input signal, and a processor. The processor processes the input signal using a gain. The processor includes an inhibitor, which inhibits distortions, and an adjuster, which adjusts the gain. The inhibitor acts to smooth an envelope of the input signal to inhibit undesired modulation. The adjuster adjusts the gain if the envelope is either above or below a threshold.
