WebMay 10, 2024 · While the binaural minimum variance distortionless response (BMVDR) beamformer provides a good noise reduction performance and preserves the binaural cues of the desired source, it does not allow to control the reduction of the interfering sources and distorts the binaural cues of the interfering sources and the background noise. WebThe objective of binaural noise reduction algorithms is not only to selectively extract the desired speaker and to suppress interfering sources (e.g., competing speakers) and ambient background noise, but also to preserve the auditory impression of the ...

WebJun 22, 2024 · HA studies investigating binaural beamforming have shown a trade-off between improvement in SNR on the one hand, and a deterioration of binaural cues on the other [Kidd et al., 2015; Picou et al., 2014]. The acoustic conditions play a critical role, as more static and/or predictable listening conditions result in more effect of binaural ...
