| 20120328112 | REVERBERATION REDUCTION FOR SIGNALS IN A BINAURAL HEARING APPARATUS - 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.
