Noise attenuation (NAseg) vs. speech component quality \((\text {PESQ}(\tilde {\mathbf {s}}))\) for different parameters α and β for the new 3CL (11) on 12.5% of the validation set. From top to bottom, the markers are corresponding to six SNR conditions from 20 to −5 dB with a step size of 5 dB. The selected setting is 
in the legend. All curves marked by 
fulfill \(\alpha =\frac {1-\beta }{2}\), meaning that the noise attenuation and the speech distortion contribute equally to the 3CL loss (11)
