Pitch can be modeled as a positional sensation scaled by discrimination steps

Evidence

Assuming that pitch belongs to the sensations of position, it is possible to construct the relationship between pitch and frequency by using the fact that a just-noticeable increment in frequency leads to a constant increment in sensation, independent of frequency. — Professor Dr.-Ing.
