Slow envelope fluctuations up to 16 Hz predict consonant-in-noise perception.
Evidence
The overall larger predictive power obtained with Pmod indicates that slow envelope fluctuations up to 16 Hz are a good predictor for consonant-in-noise perception. This is consistent with the findings by Gallun and Souza ( 2008 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5575

The predictions obtained in Sect. 4 with the energy-based (P) and the modulation-based (Pmod ) pre-processing stages both accounted for the trends in the perceptual data with respect to the considered stimulus-related sources of variability. Consonant recognition was strongly underestimated using P and well-predicted using Pmod . An inspection of confusion matrices suggested that both models correctly predicted most of the perceptual confusions, albeit with some “false alarms”.
