As we consider that the propagation noise on the ground line of interconnection between audio equipment affect their playback sound quality and integrity, we tested AC coupling of the signal ground on the single-ended analog audio transmission line between audio equipment. From subjective evaluation results, we found this AC coupling method improved subjective playback sound quality. Therefore, in this study, we measured the propagation noise current waveforms of the ground line and inter-modulation distortion in their playback audio waveforms for investigation on the sound quality improvement effect and the mechanism of the AC coupling of ground connection between audio equipment. As a result, we confirmed effects of AC coupling of the ground connection on propagation noise suppression and inter modulation distortion suppression. |
