Binaural Masking Level Differences (BMLD) measured in 12 listeners with normal hearing (gray diamonds). The tested frequencies of the tone were 250, 500, 750, 1000, 1500, and 2000 Hz. The IPD of the noise was varied from 0 to 5π in steps of 0.5π, leading to a frequency dependent ITD. For example, an IPD of π corresponds to an ITD of the noise of 1 ms at 500 Hz and to 0.5 ms at 1000 Hz. Additionally, the IPD of $\frac{3\pi }{4}$ corresponding to an ITD of 0.75 ms at 500 Hz was measured for all frequencies, which corresponds approximately to the maximum anatomically achievable ITD considering human head size. Two model versions were used: one with 1 ERB wide auditory filters and one with 2.3 ERB wide auditory filters.
