Document Summary
Ild works best for higher frequencies bc the head creates this sound shadow. The higher frequencies are the ones that are actually absorbed by the head, so we don"t pick up on the level differences. Time differences (itd) work best for low frq sounds. Level differences (ild) work best for high frq sounds. Cones of confusion: positions in space where sounds create the same time and level. Purple: people say it"s the same location. differences. The most confusing: the plane that cuts right through you: above, in front, below, behind. By doing this, we get a whole bunch of new info and by reconciling between those we pick the option that is possible and makes sense. The shape of our external ear helps us determine localization of sound. Directional transfer function: how our external ear structure changes intensity of sounds with different frequencies that arrive at each ear from different localizations in space.
