WebTo obtain a useful signal, we used the spectral approach to remove noise. The best signals were obtained at a distance of 10 mm (SNR median is 63). Good quality signals were also obtained at distances of 6 and 8 mm (SNR medians are 49 and 55, respectively). It was found that calculated BF is directly proportional to the source-detector separation. WebSep 7, 2024 · I'm doing a project about speech processing.
