Table 2 Explanation of investigated attributes of the processed signal along with possible related impairments

From: Binaural noise reduction via cue-preserving MMSE filter and adaptive-blocking-based noise PSD estimation

Attribute Meaning Possible impairment
Speech quality Utilitarian comparison of the speech quality w.r.t. the assumed original Speech onset suppression, artificial reverberation, or speech spectral smearing
Background noise attenuation Noise attenuation Noise level was annoying or unacceptably loud
Residual noise naturalness Naturalness of the residual noise Musical noise perception
Speech spatial sound cues Consistency of speech spatial cues w.r.t. simultaneous visual cues Spatial desynchronization
