A tone matching the masker-signal spectral distance degrades beating-cue detection more than other interferers

Evidence

The behavioural results of the present study support the hypothesis that modulation cues affect detection of a diotic target in masking pattern experiments and that an additional interfering tone with the same distance below (or above) the masker as the spectral distance of the signal spectrally above (or below) the masker makes the beating cue between signal and masker less usable for detection. The present study shows that the same spectral distance masker-target and interferer-masker increases thresholds more than an interferer at a different spectral distance. This result points towards a modulation spectral selectivity as previously observed in MDI experiments. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3494
