Personnalisation de l’écoute binaurale par modèle déformable d’oreille

Abstract : The term "binaural" refers to the field of research dedicated to the understanding and mastering of the mechanisms allowing humans to perceive the spatial origin of sounds. This perception emerges from our ability to detect some specific indices of localisation within our sound environment and these indices, for their part, arise from the interaction of sounds with our body and, more specifically, our ears. To reproduce a sound spatialisation effect with headphones, it is therefore necessary on the one hand to reintroduce these indices and on the other hand to personalise their generation by adapting it to the morphology of the listener.To achieve this, we have imagined an original pro- cess based on the use of a 3D morphable model of the ear and the study of the relationships between morphologies and HRTFs. Here we demonstrate its feasibility by putting it into practice thanks to synthetic databases created for the occasion. This data generation has led us to suggest optimisations for numerical computation of HRTFs and to propose possible improvements to make their sub- jective rendering more reliable.
