Steady-state interaural phase following responses were more robust than responses to slow sweeps.

Evidence

This was not the case for the lowest IPM rate where significant responses were observed for only seven subjects. In terms of spectral magnitude, responses obtained at the intermediate IPM rate showed the largest magnitude at the second harmonic, i.e. the harmonic corresponding to the IPM rate, consistent with the hypothesis that a following-response (FR) is evoked by IPM. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2976
