binaural masking level difference for pure tone signals

Journal of Otology 2023年第3期18卷 160-167页

The binaural masking level difference(BMLD)is a psychoacoustic method to determine binaural interaction and central auditory *** BMLD is the difference in hearing thresholds in homophasic and antiphasic *** duration,phase and frequency of the stimuli can affect the *** main aim of the study is to evaluate the BMLD for stimuli of different durations and frequencies which could also be used in future electrophysiological *** this end we developed a GUI to present different frequency signals of variable duration and determine the *** different durations and five different frequencies are *** results of the study confirm that the hearing threshold for the antiphasic condition is lower than the hearing threshold for the homophasic condition and that differences are significant for signals of 18ms and 48ms *** objective binaural processing studies will be based on 18ms and 48ms stimuli with the same frequencies as used in the current study.
