Webthe binaural cues of all components in the acoustic scene well preserved. Binaural beamforming methods with good capabilities to reduce the noise and preserve the binaural cues not only for the target source but also for the noise sources have been extensively researched for hearing aid applications. Some WebBased on these facts, in this thesis we try to preserve only the ILD cues of the noise components at frequencies above 1.5 kHz, while keeping the target signal undistorted. We investigate whether doing so saves the degrees of freedom that can be used to improve the noise reduction performance, in contrast to preserving both the cues.
