(57) Device for the spatial codification of sounds comprising a microphonic support shaped
like a human head, equipped with auricles and internal cavities which faithfully reproduce
the auditory meatus, the Eustachian tubes and the oral cavity, as well as with a wig
which provides asymmetry for front and back discrimination and with two microphones
arranged in the meatus cavity in the exact position and orientation as the eardrum
and in communication in the back with the cavities acting as the Eustachian tubes.
The oral cavity is in communication with the outside.
