Predicting Binaural Masking Level Difference and Dichotic Pitch Using Instantaneous ILD Model

A recently proposed auditory model is examined using simulated binaural masking level difference (BMLD) and dichotic pitch (Huggins and binaural edge pitch) stimuli. The model is based on calculating the instantaneous interaural level difference, i.e. the difference between the left and right ear neural signals. The model output produces pronounced maximum at the signal frequency with BMLD stimulus. Both dichotic pitch stimuli produce a notable maxima at the pitch frequencies. Although the model can thus be interpreted to predict known psychoacoustical results, an exact quantitative comparison with the model responses and data from BMLD and binaural pitch experiments is not performed. Rather, this paper serves as a ”proof of concept”.
