| Abstract(in English) | Have the development of sound-reproducing systems finished already? Although the digital sound systems have been advanced, the sound quality of those systems has not reached yet, the level of sound quality at the deep and hot live performance. To resolve the problem, we have introduced High Order Sensation (HOS) that is evoked from deep music, and we will aim to reproduce HOS by the digital sound system. We have developed the sound-reproducing system that could reproduce "deepness". In this paper, we have focused on the reproduction of "dignity". We have found that balanced circuits can reproduce "transparent", "deepness" and "elegant". Therefore, we have analyzed the relationship between the amounts of psychology ("transparent", "deepness" and "elegant") and the physical factors (characteristics) on Amplifier. As the result, we have clarified that the common mode noise is seriously related with the reproduction of "transparent", "deepness" and "elegant". In this paper, we will describe detail of the experiments and research process that come in the result to prove Miyahara's hypothesis. On the other hand, we have found the balanced circuit's disadvantage that is luck of "energetic". And, we have discussed how to improve the defect. |
