Binaural unmasking is phenomenon of auditory perception discovered by Ira Hirsh. In binaural unmasking, the brain combines information from the two ears in order to improve signal detection and identification in noise. The phenomenon is most commonly observed when there is a difference between the interaural phase of the signal and the interaural phase of the noise. When such a difference is present there is an improvement in masking threshold compared to a referen… WebAbstract Large binaural masking-level differences (BMLDs) can be observed when a tonal signal with an interaural phase difference of π is presented against a diotic masker. The BMLD is large when the signal is spectrally centered in the masker and decreases strongly for off-frequency signals.
