| Research Abstract |
Performance of audio equipment is often evaluated subjectively. That of audio cables is also evaluated subjectively. However, there are few studies of them because of being difficult to finding the difference of acoustical characteristics of them.In this study, we were able to visualize the very small frequency changes in the TSP audio signal passed through the audio cables by using the NHA（Non-Harmonic Analysis). From the results, we got new knowledge about the relationship between the electrical characteristic and the subjective evaluation of cables.
