WebMay 26, 2024 · The binaural beamforming strategy of primax, which can provide Narrow Directionality, is similar to that of its predecessor, binax (see Kamkar-Parsi4 et al for a review of this processing). 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 ...
