Interaural time difference
Videos
The interaural time difference when concerning humans or animals, is the difference in arrival time of a sound between two ears. It is important in the localization of sounds, as it provides a cue to
Interaural time difference (ITD) between left (top) and right (bottom) ears. (sound source: 100 ms white noise from 90° azimuth, 0° elevation)
John William Strutt, 3rd Baron Rayleigh, was a British physicist and hereditary peer who received the Nobel Prize in Physics in 1904 for his discovery of argon.
Interaural time difference
…amplitude-modulated stimulus IPD can be assessed by looking at either the waveform envelope or the waveform fine structure. The duplex theory proposed by Lord Rayleigh (1907) provides an explanation for the ability of humans to localise sounds by time differences between the sounds reaching each ear (ITDs) and differences…
