In the location of sound of 800 Hz, is it easier to detect the direction of the origin of the sound if the sound is coming from the side of the head or if the sound is coming from the midline at the back of the head? Explain your answer in terms of ITD & ILD. WebSound localization is the ability to tell the direction from which a sound is originating. When sound localization ability is low, it affects a person's safe interaction in an environment. Lack of sound localization ability can influence safe movement in public spaces. If a person cannot tell the direction of an approaching vehicle, with or ...

If the direction of the sound waves is not from the sides, but rather from above, below or immediately in front of the face, there is no time lag between the ears.
