WebMasking Level Difference (MLD) testing has become an important addition to clinical audiology test batteries. Although data are available relating the MLD to a variety of pathological conditions, little information exists dealing with learning disabled individuals. This study presents normative MLD data for a population of 90 learning disabled … 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.

Off-frequency BMLD: the role of monaural processing - PubMed

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 degeneration of the inferior colliculus would result in a reduction of the BMLD in humans.
