Spectral modulation threshold is the smallest detectable spectral contrast in a stimulus.

Evidence

One measure of spectral resolution is the spectral modulation threshold (SMT), which is defined as the smallest detectable spectral contrast in the spectral ripple stimulus (Litvak et al. 2007 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1823
