Interferer effects on masked auditory thresholds peak when interferer-masker and masker-target distances match

Evidence

Threshold was highest when the spectral distance masker-target and interferer-masker threshold was the same. It was 4.5 dB lower when the interferer was positioned 30 Hz instead of 100 Hz below the masker. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3483
