A suppressor below masker threshold can reduce forward masking without itself masking the signal

Evidence

For each participant, several suppressor levels were presented, and the level producing the greatest amount of suppression was used for analysis. The suppressor was an average of 4 dB below the off-frequency masker threshold obtained in Experiment 1 [SD = 1.60]. For younger adults, suppressors were presented at an average of 74.50 dB SPL [SD = 5.22] for low-side suppression and 74.23 dB SPL [SD = 4.00] for high-side suppression. For older adults, suppressors were presented at an average of 67.60 dB SPL [SD = 2.12] for low-side suppression and 75.20 dB SPL [SD = 3.68] for high-side suppression. — Dijk, Pim van, Physiology, Psychoacoustics and…, 940
