摘要： A hearing aid includes an input unit, an output unit, a signal processing unit connected to the input unit and output unit, where the input unit, the signal processing unit and the output unit form part of a forward path of the hearing aid, where the signal processing unit is configured to apply a forward gain to the at least one electric input signal or a signal originating therefrom. The hearing aid further includes a feedback reduction unit configured to reduce risk of howl due to acoustic, electrical, and/or mechanical feedback of an external feedback path from the output unit to the input unit. The feedback reduction unit is configured to modulate the forward gain in time to provide that the forward gain exhibits an increased or unchanged forward gain in one or more first time periods and a reduced forward gain in one or more second time periods.

摘要： A hearing aid includes an input providing an input signal representing sound in an environment, the input signal including no speech signal, or one or more speech signals from one or more speech sound sources and additional signal components, termed noise signal, from one or more other sound sources, an own voice detector, a voice activity detector, and a talker extraction unit to determine and/or receive one or more speech signals as separated one or more speech signals from speech sound sources other than the hearing aid user and to detect the speech signal originating from the voice of the user. The talker extraction unit provides separate signals, each including, or indicating presence of, one of the one or more speech signals. A noise reduction system determines speech overlap and/or gap between the speech signal originating from the user's voice and each of the separated one or more speech signals.

摘要： A hearing aid comprises a forward path comprising an input transducer an electric input signals representing a sound comprising target signal components and background noise, a hearing aid processor for providing a processed signal in dependence of said at least one electric input signal and for providing a processed output signal in dependence thereof, and an output transducer for providing stimuli perceivable as sound to the user in dependence of said processed signal. The forward path provides a frequency dependent intended forward path transfer function. The hearing aid further comprises a feedback path estimator configured to provide a current frequency dependent estimate of a feedback path transfer function of a feedback path from the output transducer to the input transducer, and a current feedback path estimate in dependence of the current estimate of the feedback path transfer function and of the processed signal, and a combination unit in the forward path configured to subtract the current feedback path estimate from a signal of the forward path to provide a feedback corrected signal. The hearing aid may further comprise a noise estimator configured to provide a current frequency dependent noise estimate representing a background noise level in the at least one electric input signal, an open loop transfer function estimator configured to provide a frequency dependent estimate of a current open loop transfer function in dependence of the intended forward path transfer function and the current estimate of the feedback transfer function, and a confidence level estimator configured to provide a current frequency dependent estimate of a confidence level of the current estimate of the feedback transfer function in dependence of a current estimate of open loop gain and optionally the current noise estimate. The hearing aid may be configured to control processing in the hearing aid in a frequency band k in dependence of said current estimate of the open loop transfer function and/or the current estimate of the feedback path transfer function, if the current estimate of the confidence level fulfils a confidence criterion in said frequency band k. A method of operating a hearing aid is further disclosed. The invention may e.g. be used to assess a risk of acoustic feedback in a hearing aid.
