Abstract: This paper proposes an objective speech distortion measure as a substitute for human auditory systems. Simultaneous and temporal masking effects are introduced into this measure called auditory-oriented Spectral Distortion(ASD). We calculate the ASD using spectral components over masked thresholds in the same way as the Spectral Distortion(SD). We confirmed that the ASD is more compatible to subjective mean opinion score that represents distortions on auditory impression than the SD. We applied the ASD to optimize a noise reduction algorithm proposed by the authors, and confirmed that this optimized algorithm reduces noises appearing to the ear. ASD is sure to be an available guide to design noise reduction algorithms.
