The masking-level difference in children.
The masking-level difference (MLD) was investigated in children aged 3.9 to 9.5 years and in an adult control group in order to examine the development of the MLD with age. A three-alternative forced-choice adaptive tracking procedure was used for all listeners. MLDs were determined for a 500-Hz pure-tone signal presented in a 300-Hz-wide masking noise centered on 500 Hz, where both interaural ...
متن کاملHuman frequency-following responses to binaural masking level difference stimuli.
Binaural masking level difference is the behavioral threshold difference between a diotic condition (SoNo) and a dichotic condition with a 180 degrees interaural phase delay of either the signal (SpiNo) or the masker (SoNpi). Threshold disparity is partially related to coincidence-detecting units in the medial superior olive that are sensitive to low-frequency binaural stimuli with interaural p...
متن کاملFunctional Anatomy of the Masking Level Difference, an fMRI Study
INTRODUCTION Masking level differences (MLDs) are differences in the hearing threshold for the detection of a signal presented in a noise background, where either the phase of the signal or noise is reversed between ears. We use N0/Nπ to denote noise presented in-phase/out-of-phase between ears and S0/Sπ to denote a 500 Hz sine wave signal as in/out-of-phase. Signal detection level for the nois...
متن کاملThe masking-level difference in low-noise noise.
In experiment 1 NoSo and NoS pi thresholds for a 500-Hz pure tone were obtained in a low-fluctuation masking noise and a high-fluctuation masking noise for six normal-hearing listeners. The noise bandwidth was 10 Hz. In agreement with previous investigations, the NoSo thresholds were lower in low-fluctuation noise than in high-fluctuation noise. For three listeners, NoS pi thresholds were simil...
متن کاملMeasurement of the 2f1-f2 cubic difference tone with the binaural masking-level difference.
Stimulus-like properties of the 2f1-f2 cubic difference tone (CDT) were examined by determining whether a binaural masking-level difference (BMLD) could be obtained for a 500-Hz physical tone to one ear and a CDT of the same frequency to the other ear. Masked thresholds for the physical tone (signal) were obtained as the phase of this tone varied through 360 degrees relative to harmonically rel...
