Interfering noises resembling speech’s modulation fool attention and exceed their level
Evidence
Interfering noises that have similar rates of variation as speech are particularly difficult to deal with, as they fool our higher-order processing centers into attending to them as if they are speech. Because of this, their effect is often more severe than a simple measurement of level would indicate. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 2481 (
