1. A method for transmitting a target sound to a listener, comprising: (4) (5)

comprising:

receiving microphone signals including the target sound from microphones;

processing the microphone signals using a neural network to produce a processed signal including the target sound, the neural network including a linear signal processing path and a nonlinear signal processing path;

producing an output signal including the target sound using the processed signal; and

producing an output sound based on the output signal using a speaker.

2. The method of claim 1, wherein processing the microphone signals using the neural network comprises processing the microphone signals to improve intelligibility of speech in a noisy background, the speech being the target sound. (0)

3. The method of claim 1, further comprising training the neural network with a synthesized target sound in a noisy condition and a specified cost function. (1) (0)

6. The method of claim 1, wherein processing the microphone signals comprises using the nonlinear signal processing path to increase a signal-to-noise ratio (SNR) for the target sound and using the linear signal processing path to decrease distortion of the target sound. (0)

7. The method of claim 1, wherein receiving the microphone signals comprises receiving at least microphone signals from a pair of hearing devices worn by the listener. (3) (0)

11. A hearing system for transmitting a target sound to a listener, comprising: (3) (3)

microphones configured to receive input sounds including the target sound and to produce microphone signals using the input sounds;

a control circuit configured to produce an output signal using a processed signal and including a neural network, the output signal including the target sound, the neural network including a linear signal processing path and a non-linear signal processing path and configured to produce the processed signal by processing the microphone signal through the linear and non-linear signal processing paths; and

a speaker configured to produce an output sound using the output signal.

12. The system of claim 11, comprising a pair of hearing devices configured to be worn by the listener and an external device configured to be communicatively coupled to the hearing devices, and wherein the microphones comprises a microphone placed in each of the hearing devices. (4) (0)

17. The system of claim 11, wherein the target sound is speech, and the neural network is configured to improve speech intelligibility. (2) (0)

20. The system of claim 11, wherein the neural network comprises: (0) (3)
