(a) Average results with error bars on the evaluation of objective, quality, and intelligibility measures for original noisy signal (left bar) and the enhanced signal (right bar), compared with noise as the ground truth. Enhanced signals were found to be more “distant” representations of the noise signals. Stars indicate statistically significant differences. (b) Average responses of the listening text where bars indicate the preference percentage per choice. Left: overall results, comparing average preference of the original sounds versus preference of any of the enhanced versions. Panel [A to Any] includes choices {A, B, C, D, Any}; Right: the breakdown among all choices. Choice Any of A,B,C,D has been abbreviated to Any.
