| 抄録: | Fundamentally speaking, audio system should be faithfully reproduced deep sensations of human that evoke deep musical emotions such as “atmospherics”, “feel of tension” and “texture of sound”, etc. It is possible to construe faithful reproduction of deep sensations in audio system as an example of process to translation from tacit knowledge into the other tacit knowledge. Therefore, development of audio systems which can faithfully reproduce deep emotions is possible to say the same as “Socialization” in SECI model. However, most of existing audio system can not reproduce such as deep musical emotion. For this purpose, we have been developed such as audio systems focused on the deep musical sensations. In our researches, we found jitter in digital audio systems deteriorate sound quality seriously. In this paper, at first, we investigate the relation between sound quality concerned with deep sensations and jitter in digital audio systems. Accordingly, we speculated that the influence of jitter was transformed to other shapes before or within the D/A converter block. One of the possibilities is that the influence of the jitter affects the sound quality, indirectly, via the power supply line. Secondarily, we attempted to clarify the relation of sound quality and an ideal power supply of audio systems. The measurement result showed the proposed power supply can suppress the turbulence comparing with conventional ones. The assessment result showed that the MOS value of sound quality of the proposed power supply was higher than conventional ones. |
