A stringed instrument’s pluck position can be read from harmonic amplitude dips.

Evidence

For the purposes of our simple model, the sound source is known as the “input” and the sound modifiers are known as the “system.” The result of the input passing through the system is known as the “output.” — David Howard, Jamie Angus, coustics and Psychoacoustics, 1081 (#exemplifies, via linked claim)
