摘要:
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.

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.

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.
摘要:
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.
