Masking noise prevents listeners from using unintended spectral cues

Evidence

Unlike physiological experiments, where we can measure the response elicited by a single stimulus, a masking study always involves at least two sounds: a signal and a masker. The signal is the sound being detected, whereas the masker is the interfering sound. Often the signal is a pure tone, but in principle, it can be any type of sound, such as speech and complex sounds. The same is true for the masker; it can be any type of sound such as noise, speech, or tones. In these studies, by measuring the influence of a masker on a signal, we can make inferences about how the signal or the masker is represented by the auditory system. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 441 (#expands, via linked claim)
