A hearing device includes a deep/recurrent neural network trained to jointly perform sound enhancement and feedback cancellation. During training a neural network is connected between a simulated input and a simulated output of the hearing device. The neural network is operable to change a response affecting the simulated output. The neural network is trained by applying the simulated input to the deep neural network while applying the feedback path response between the simulated input and the simulated output. The deep-neural network is trained to reduce an error between the simulated output and the reference audio signal and used for sound enhancement in the device.

A method including obtaining data based on a current and/or anticipated future state of a hearing prosthesis and adjusting a set gain margin of the hearing prosthesis based on the current or anticipated future state of the hearing prosthesis.

Systems and methods for detecting when a device is placed into an operational position are disclosed. Upon determination that the device is in the operational position, one or more processes can be executed. Execution or initialization of the processes upon detection of the operational position provides for the determination of optimal settings than would otherwise be determined if the processes automatically executed before detection of the operational position. Further aspects of the present disclosure relate to determining when the device is no longer in an operational position upon which time the execution of the processes are terminated. The settings in place upon termination can be saved and reapplied the next time the device is in the operational position.

A system for reducing noise in a drive signal of a hearing device, including a microphone operative to receive sound and generate a microphone output signal and an adaptive filter apparatus that receives a signal from a transducer separate from the microphone and outputs a filtered signal, wherein the system subtracts the outputted filtered signal from a signal based on the microphone output signal to cancel noise and outputs the resulting signal, and the system further processes the resulting signal to obtain a further processed resulting signal to remove and/or eliminate residual feedback present in the resulting signal.
