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… WebDec 15, 2014 · Neural correlates of this binaural masking level difference (BMLD) have been observed in the inferior colliculus and temporal cortex, but it is not known whether … how does the oreck air purifier work

For lateral sources the sound arrives later at the contralateral ear, because the sound must travel farther from the source to this ear, thus generating an ITD between both ears.
