Binaural detection advantages act on small spectro-temporal units, not whole frequency bands
Evidence
We will therefore consider BMLD effects at the level of spectro-temporal regions rather than frequency channels. Thus we extend the original hypothesis and postulate that a BMLD effect might take place at the level of individual spectro-temporal units and that this detection advantage would be responsible for the spatially improved speech intelligibility. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1623
