Hrtf Individualization by Finite Element Modeling Coupled with a Corrective Model

A method of modeling transfer functions HRTFs specific to an individual, wherein there are provided:

• an initial model construction step in which:
• a) a first database is constructed, including a plurality of HRTFs measured in a multiplicity of directions of the space and for a plurality of individuals,
• b) a second database is constructed, including specific and respective morphological parameters of said plurality of individuals,
• c) from said morphological parameters of the second database, a finite element modeling is applied to obtain a third database including specific and respective modeled HRTFs of said plurality of individuals, for at least some of said multiplicity of directions,
• d) by comparison and learning on the data from the first and third databases, a corrective model is constructed that is suitable for giving HRTFs that are modeled and adjusted for said multiplicity of directions,
• and a current step for determining the HRTFs in said multiplicity of directions, for any individual, in which:
• e) morphological parameters of the any individual are measured, and
• f) modeled and corrected HRTFs of the any individual are obtained by applying the finite element modeling and said corrective model to the morphological parameters of the any individual.
