Local synthesis of a sound field by a virtual diffusion body

摘要

Procedure for defining the excitation signals for reproduction of a sound field and within a local area of ​​the listeners through multiple speakers placed at locations outside the scope listeners, with the following steps: - definition of a virtual sound field externally circulated to the field of listeners, which is created by the diffusion of sound field in a body of virtual broadcast with a geometry equivalent to the geometry of the field of listeners, the body having virtual broadcast conditions marginal acoustically soft, acoustically hard or mixed; - investment of time signals broadcast virtual sound field.
