A propósito de espacialización y de las HRTFs
Malcolm Slaney escribe:
We all know that our two ears can use intensity and timing
differences to tell us from which direction a sound is coming from.
But there are a whole cone of sounds, the cone of confusion, that
share the same timing cues. How is that we tell how high the sound
is coming from?

Pinna Models and Elevation Cues
It has long been known that the outer ears or pinnae provide the
primary static acoustic cues for elevation. This has driven numerous
efforts at measuring and modeling individualized HRTFs. However,
despite considerable research, the exact nature of these cues is not
well understood. Furthermore, there are other cues for elevation,
and in some circumstances they can dominate pinna cues. We will
review the state of knowledge in this area, and describe a simple
model that appears to be capable of fitting experimental data.
