In this paper we propose a method for reducing the impact of room reflections in sound field rendering applications. Our method is based on the modeling of the acoustic paths (direct and reflected) from each of the loudspeakers of the rendering system, and a set of control points in the listening area. From such models we derive a propagation matrix and compute its least-squares inversion. Due to...
In this paper we propose a method for reconstructing the 2D geometry of the surrounding environment based on the signals acquired by a fixed microphone, when a series of acoustic stimula are produced in different positions in space. After estimating the Times Of Arrival (TOAs) of the reflective paths, we turn each TOA into a projective geometric constraint that can be used for determining the locations...
