dc.description.abstract	Broadband local sound field reproduction over an extended spatial region is a challenging problem, when only limited transfer function measurement is available. In this paper, an acoustic modelling based approach is proposed to reduce the required transfer function measurements in the local sound field reproduction. The proposed method only requires measuring the transfer functions from each source to a few samples over the boundary of the controlled region, and the transfer functions to the samples inside the controlled region are estimated through an efficient acoustic modelling. The simulation demonstrates that the proposed method requires less transfer function measurement than existing methods such as the least squares and the spatial harmonic decomposition methods.

Abstract:

Broadband local sound field reproduction over an extended spatial region is a challenging problem, when only limited transfer function measurement is available. In this paper, an acoustic modelling based approach is proposed to reduce the required transfer function measurements in the local sound field reproduction. The proposed method only requires measuring the transfer functions from each source to a few samples over the boundary of the controlled region, and the transfer functions to the samples inside the controlled region are estimated through an efficient acoustic modelling. The simulation demonstrates that the proposed method requires less transfer function measurement than existing methods such as the least squares and the spatial harmonic decomposition methods.
