Binaural masking level difference
WebBinaural masking level differences in actual and simulated bilateral cochlear implant listeners Thomas Lua Department of Otolaryngology–Head and Neck Surgery, University … 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.

WebThe Masking Level Difference (MLD) test is one of the main instruments for investigating binaural interaction. Studies with children aged 7–12 years still disagree about the influence of age on test performance and present discordant reference values. WebAug 13, 2024 · Binaural unmasking relies on differences in the timing of the sound at the two ears (Interaural Time Differences, ITDs). 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.

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.
