Further Evidence Of The Contribution Of The Ear Canal To Directional Hearing: Design Of A Compensating Filter, Andrea Martelloni, Davide Andrea Mauro Phd, Antonio Mancuso

Computer Sciences and Electrical Engineering Faculty Research

It has been proven, and it is well documented in literature, that the directional response in HRTFs comes largely from the effect of the pinnae. However, few studies have analysed the contribution given by the remaining part of the external ear, particularly the ear canal. This work investigates the directionally dependent response of the modelled ear canal of a dummy head, assuming that the behaviour of the external ear is sufficiently linear to be approximated by an LTI system. In order to extract the ear canal's transfer function, two critical microphone placements (at the eardrum and at the beginning of …
