Document Summary
Depends on standard (pitch is measured in mels perceptual dimension) (frequency is measured in hz physical dimension) Pitch is our sense of the frequency, however they are not equal. To go from 1000 ml to 2000 ml, you have to raise frequency 1000 hz to 3000 hz. It is not a linear curve (like half a bell curve) At high frequencies increase in the amplitude of a pure tone also causes an increase in the perceived pitch. No, because the harmonics in the complex tone prevent a shift in perceived pitch (musical instruments are not pure tones they are harmonics and the harmonics helps stabilize the perception of pitch) Without harmonics, intensity would interact with sensation of pitch. Harmonics also causes a challenge for static frequency missing fundamental problem. Sound like they have similar perception despite the fact that in the frequency plots, all the low frequencies have been removed and only the higher frequencies have been left.
