Speech masking in noise stems from inherent temporal-envelope modulations rather than overall noise energy.

Evidence

Recent work has suggested that it is not so much the overall noise energy that limits speech perception in noise, as suggested by earlier work (French and Steinberg 1947 ; Kryter 1962 ; George et al. 2008 ), but rather the energy in the inherent temporal-envelope modulations in noise (Dubbelboer and Houtgast 2008 ; Jorgensen and Dau 2011 ; Stone et al. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2164
