How do you calculate interaural time delay?
Interaural Time Difference (ITD)
The time difference between the two ears will be the difference in the left and right distances divided by the speed of sound. Here's a plot of the ITD for our sound as a function of time: ITD = 1000*(tauR-tauL); clf plot(t,ITD); xlabel('Time (s)'); ylabel('ITD (msec)');
Where are interaural time differences computed?
In mammals, the primary nucleus to extract fine structure interaural time differences (ITDs) is the medial superior olive (MSO), while the interaural level differences (ILDs) are extracted primarily at the lateral superior olive (LSO) (Grothe et al., 2010).
