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… WebBinaural masked thresholds for a speech sound [ba] were estimated under two interaural phase conditions (NoSo and NoS pi) in three age groups (infants, preschool children, and adults).
