摘要： A hearing device, e.g. a hearing aid or a headset, configured to be worn by a user at or in an ear or to be fully or partially implanted in the head at an ear of the user comprises an input unit for providing at least one electric input signal in a time-frequency representation and a signal processor comprising a neural network configured to provide respective gain values G ( k , t ) in said time-frequency representation for reducing noise components in said at least one electric input signal. The neural network comprises at least one layer defined as a modified gated recurrent unit, termed Peak GRU, comprising memory in the form of a hidden state vector h, and wherein an output vector o is provided by said Peak GRU in dependence of an input vector x and said hidden state vector h, wherein an output o ( j , t ) of the Peak GRU at a given time step t is stored as said hidden state h ( j , t ) and used in the calculation of the output o ( j , t +1) in the next time step t+1. The signal processor is configured to provide that the number of updated channels among N ch processing channels of the Peak GRU for said input vector x(t) and said hidden state vector h ( t -1) at said given time instance t is limited to a number of peak values N p , where N p is smaller than N ch . A method of operating a hearing device is further disclosed.

摘要： A hearing aid system configured to compensate for a hearing impairment of a use comprises A) a wearable device adapted for being worn by the user and comprising a1) an input stage comprising at least one input transducer for converting sound around the user to at least one electric input signal representing said sound, and a2) an input stage for providing stimuli representative of a processed version of said least one electric input signal to said user, said stimuli being perceivable by said user as sound; and B) a non-wearable device comprising b1) a processor, and b2) a power supply interface for providing power to the processor. The wearable device and the non-wearable device comprise respective transceiver circuitry for establishing a low latency wireless audio communication link between them. The processor of the non-wearable device comprises an audio processor configured to process said at least one electric input signal, or a signal originating therefrom, to at least partially compensate for the hearing impairment of the user and to provide said processed version thereof. The power supply interface of the non-wearable device is electrically connected to an electricity network. Thereby an improved processing power of a hearing aid may be provided. The invention may e.g. be used in flexible hearing aid systems with a situation-dependent configurable processing power.

摘要： A method, comprising: at a hearing aid with a processor; a memory; an output unit; and a wireless communication unit: receiving, via the wireless communication unit, a wireless signal including a succession of frames including a first frame including first encoded audio samples; and determining a first codec; performing an error check based on the first frame; and in accordance with a determination that the first frame fails to pass the error check: performing a test, including determining first difference values between first expected histogram values in categories and first observed histogram values of the first encoded audio samples in the categories; wherein the expected histogram values are associated with the first codec; and determining a first fitness value associated with the first difference values; wherein the first expected histogram values are stored in the memory; in accordance with a determination that the first fitness value satisfies a first criterion, enabling rendering of the first encoded audio samples via the output unit. The wireless communication unit may be a Bluetooth Low Energy wireless communication unit.
