Abstract:
1. A method for direction dependent spatial noise reduction, which comprises the following steps: measuring an acoustic input signal from an acoustic source; obtaining, from the acoustic input signal, at least one monaural directional signal and at least one binaural directional signal; estimating a target signal level by combining the at least one monaural directional signal and the at least one binaural directional signal, the at least one monaural directional signal and the at least one binaural directional signal mutually have a maximum response in a direction of the acoustic source; and estimating a noise signal level by combining the at least one monaural directional signal and the at least one binaural directional signal, the at least one monaural directional signal and the at least one binaural directional signal mutually have a minimum sensitivity in a direction of the acoustic source.
