MODELING OF ACOUSTIC TRANSFER FUNCTION ASSEMBLY OF AN INDIVIDUAL, THREE-DIMENSIONAL CARD AND THREE-DIMENSIONAL REPRODUCTION SYSTEM

摘要

The invention relates to the modeling of individual acoustic transfer functions relating to the hearing of an individual in three-dimensional space. An object of the invention is a method for modeling sets of acoustic transfer functions specific to an individual according to a multiplicity of directions of space, in which a set of acoustic transfer functions specific to an individual in a given direction multiplicity of directions is determined according to the result of a statistical analysis of several distinct stimuli sent to the individual, a stimulus being a function of at least one set of predetermined acoustic transfer functions associated with the given direction, and responses received from the individual to each stimulus emitted. Thus, the invention is more reliable and more robust than a simple selection of a set of acoustic transfer functions in a database and overcomes the disadvantage of the critical acquisition of the 3D mesh of the individual morphology used by the classical numerical modeling.
