This paper presents the construction and design of a database of 3D CAD models of heads and ears, which is intended to be used in acoustic work to obtain personalized HRTFs. This database is named PUCV

En este proyecto se exponen los antecedentes teóricos acústicos, argumentando y estableciendo la importancia del oído externo, producto de su morfología. Las pinnas son de vital importancia en las ondas sonoras, propagadas desde la fuente hasta el tímpano, y cuyos efectos logran establecer la localización espacial del sonido emitido. In this report the acoustic theoretical antecedents are exposed, arguing and establishing the importance of the external ear, product of its morphology (concavities, convexities). The pinnas are of vital importance in sound waves, propagated from the source to the eardrum, and whose effects manage to establish the spatial location of the sound emitted.
