人们皆知,音的高度是由发音物体的振动频率数决定的,而与强度(振幅)无关。但音响学家迈尔斯(Miles)在1914年发现:使两个振动频率数相同的音的强度不同时,它们的高度亦会出现小的差异。并且他还指出,如果两个音的高度都是中央C,那么在 It is well-known that the height of a sound is determined by the number of vibrational frequencies of the sounding object regardless of the intensity (amplitude). But in 1914, the audiophile Miles found that by making the difference between the intensities of two sounds of the same frequency of vibration, there is a small difference in their height. And he also pointed out that if the two tones are all in center C, then
