Abstract: A method, system, and computer program product for managing noise in a noise reduction system, comprising: receiving a first signal at a first microphone; receiving a second signal at a second microphone; identifying noise estimation in the first signal and the second signal; identifying a transfer function of the noise reduction system using a ratio of a power spectral density of the second signal minus the noise estimation to a power spectral density of the first signal, wherein the noise estimation is removed from only the power spectral density of the second signal; and identifying a gain of the noise reduction system using the transfer function.

Abstract: A more efficient method reduces reverberation in binaural hearing systems. This has been done by developing a method for obtaining a reduced-reverberation, binaural output signal, for a binaural hearing apparatus. First of all, a left input signal and a right input signal are provided. The two input signals are combined to form a reference signal. The reference signal is used to ascertain spectral weights, or these weights are provided in another way, in order to use them to reduce late reverberation. To this end, the two input signals have the spectral weight applied to them. Furthermore, a coherency for signal components of the weighted input signals is ascertained. Non-coherent signal components of both weighted input signals are then attenuated in order to reduce early reverberation.
