How HRTF Works
The associated mechanism varies between individuals, as their head and ear shapes differ.
HRTF describes how a given sound wave input (parameterized as frequency and source location) is filtered by the diffraction and reflection properties of the head, pinna, and torso, before the sound reaches the transduction machinery of the eardrum and inner ear (see auditory system). Biologically, the source-location-specific prefiltering effects of these external structures aid in the neural determination of source location), particularly the determination of the source's elevation (see vertical sound localization).

Famous quotes containing the word works:
“The whole idea of image is so confused. On the one hand, Madison Avenue is worried about the image of the players in a tennis tour. On the other hand, sports events are often sponsored by the makers of junk food, beer, and cigarettes. What’s the message when an athlete who works at keeping her body fit is sponsored by a sugar-filled snack that does more harm than good?”
—Martina Navratilova (b. 1956)
