Abstract: A hearing aid comprises an input transducer configured to convert sound around a user to at least one electrical input signal representing the sound; an output transducer for providing an audible signal based on the at least one electrical input signal; transceiver circuitry configured to establish a wireless audio communication link with a secondary device; and a processor configured to operate the hearing aid in a system mode or a device mode. The hearing aid is configured to initiate establishment of the wireless audio communication link in dependence of a mode control signal. A non-wearable device comprising transceiver circuitry configured for establishing a wireless audio communication link with a hearing aid comprises a processor configured to receive and process at least one electrical input signal from a hearing aid to at least partially compensate for hearing impairment of a user; a power supply interface. The non-wearable device is integrated with another device having a specific other function.

Abstract: A hearing device, e.g. a hearing aid or a headset, configured to be worn by a comprises an input unit for providing at least one electric input signal in a time-frequency representation; and a signal processor comprising a target signal estimator for providing an estimate of the target signal; a noise estimator for providing an estimate of the noise; and a gain estimator for providing respective gain values in dependence of said target signal estimate and said noise estimate. The gain estimator comprises a trained neural network, wherein the outputs of the neural network comprise real or complex valued gains, or separate real valued gains and real valued phases. The signal processor is configured—at a given time instance t—to calculate changes Δx(i,t)=x(i,t)−{circumflex over (x)}(i,t−1), and Δh(j,t−1)=h(j,t−1)−ĥ(j,t−2) to an input vector x(t) and to the hidden state vector h(t−1), respectively, from one time instance, t-1, to the next, t, and where {circumflex over (x)}(i,t−1) and ĥ(j,t−2) are estimated values of x(i,t−1) and h(j,t−2), respectively, where indices i, j refers to the ith input neuron and the jth neuron of the hidden state, respectively, where 1≤i≤Nch,x and 1≤j≤Nch,oh, wherein Nch,x and Nch,oh is the number of processing channels of the input vector x and the hidden state vector h, respectively, and wherein the signal processor is further configured to provide that the number of updated channels among said Nch,x and said Nch,oh processing channels of the modified gated recurrent unit for said input vector x(t) and said hidden state vector h(t−1), respectively, at said given time instance t is limited to a number of peak values Np,x, and Np,oh, respectively, where Np,x is smaller than Nch,x, and Np,oh, is smaller than Nch,oh.

Abstract: 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.
