The common counter-argument made is that frequencies above 20KHz, while not individually distinguishable to the human ear, does contribute to the harmonic richness of tones below 20KHz.

One of the most common comments made by proponents of high resolution audio make is that the sound is smoother, more analog like. I have heard the difference for myself and it is unmistakeable. But I don't believe the main benefit is in the increased frequency response, but the increased resolution afforded to frequencies within the range that the human ear can resolve.



요약하면, 20KHz 이상의 신호가 20KHz 이하의 음질에 영향을 미친다는 얘기인 것 같네요.

제 질문은요,

2. 그래프의 모양과 위 주장 사이에 연관성이 보이시는지요?



제 느낌은, "참 재미있구나" 정도입니다만.
