Abstract(in English) In speech communication at a loud ambient noise environment, users listen to human speech added to noises. Therefore the noise reduction systems are important to such environment. To provide high-quality speech communication services to users, it is important to know accurately a performance of noise reduction systems, optimize of parameter and select best one. In this paper, we showed the subjective quality evaluation characteristics of degraded speech by noise reduction systems from the viewpoint of the effects of speech distortion, noise distortion, and noise loudness. In addition, we investigated a basic model that described a relationship between the subjective quality and the three quality factors.
