Speech-shaped noise can carry intelligible masked signals through amplitude modulation
Evidence
Two different maskers were used: 20-talker babble (created by modulating a speech-shaped noise with the amplitude envelope of male sentences) or speech-shaped noise (average long-term spectrum of the sentences). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2070
