WebThe critical-band rate scale based on improved multi-band spectral subtraction is investigated in this study for enhancement of single-channel speech. In this work, the whole speech spectrum is divided into different non-uniformly spaced frequency bands in accordance with the critical-band rate scale of the psycho-acoustic model and the ... WebMulti-band FC in the brain source space was constructed using the phased lag index (PLI) method and used as features to train an SVM classification model to classify driver fatigue and alert conditions. With a subset of critical connections in the beta band, a classification accuracy of 93% was achieved.

WebThe larger the critical bandwidth the lower the signal-to-noise ratio (SNR) and the more the signal is masked. Another concept associated with the auditory filter is the equivalent rectangular bandwidth (ERB). The ERB shows the relationship between the auditory filter, frequency, and the critical bandwidth.

WebMar 13, 2024 · The comparison of band angle, in Fig. 7a, shows that a two-invariant model leads to a systematic underestimation of \(\beta\) compared to the three-invariant model.
