Performance analysis of a planar microphone array for three dimensional soundfield analysis

Samarasinghe, Prasanga; Chen, Hanchi; Fahim, Abdullah; Abhayapala, Thushara

Description

Soundfield analysis based on spherical harmonic decomposition has been widely used in various applications. However, a major drawback of this method is the requirement of spherical or alternate 3D array geometries, which are often considered to be bulky. Recently, the design of a 2D planar microphone array capable of capturing 3D spatial soundfields was proposed. This design utilizes omnidirectional and differential microphones to capture soundfield components that are undetectable to...[Show more]
