Modulation power is captured by filters tuned to 2, 4, 8, and 16 Hz

Evidence

The modulation power Pmod , in dB, was obtained using the subband envelope extraction described above, followed by a modulation filterbank consisting of 3 second-order band-pass filters (center frequencies of 4, 8, and 16 Hz) in parallel with one third-order low-pass filter (cut-off frequency of 2 Hz). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5605
