摘要:

这项工作提出了一种方法,用于估计的声强度,能量密度和相关的声场扩散周围的起源,当声场加权的空间滤波器。该方法允许能量DOA估计和声场表征集中在由空间滤波器的波束图案确定的特定角区域中。制定的估计和他们的行为进行了分析的基本情况下,有用的参数声场模型的一个单一的平面波,均匀的扩散场和两者的混合物。

英文摘要:

This work presents a method for estimation of the acoustic intensity, the energy density and the associated sound field diffuseness around the origin, when the sound field is weighted with a spatial filter. The method permits energetic DOA estimation and sound field characterization focused in a specific angular region determined by the beam pattern of the spatial filter. The formulation of the estimators is presented and their behavior is analyzed for the fundamental cases useful in parametric sound field models of a single plane wave, a uniform diffuse field and a mixture of the two.
