Abstract (en)
[origin: EP0050100A2] 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.
