Only low-numbered harmonics are resolved, higher ones blur together in the internal representation

Evidence

Individual harmonics represented only in the low frequencies. The representation of the lowfrequency harmonics is not as robust as present in the spectrum. Harmonics 1 through 8 are visible as distinct bumps in the excitation pattern, and these bumps gradually smooth as frequency increases. Harmonics 1 to 8 are considered resolved, whereas harmonics 9 and above are considered unresolved. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 509
