In order to exploit the phase information for a better 3D acoustic source enhancement, we design a novel array configuration based on three orthogonally placed Acoustic Vector Sensors (AVS), which effectively uses the directional array response in phase in addition to the one in amplitude. The proposed design is called “Phased AVS Array” (PAVSA). We compare the signal enhancement performance of our design with the well-known configurations, e.g., ULA and Spherical arrays, in terms of the noise and interference suppression. The proposed design PAVSA is experimentally shown to perform comparably to the conventional omni-directional microphone arrays, however, with significantly smaller array size and smaller number of microphones while being, moreover, superior to the enhancement performance of the 1D and 2D AVS arrangement strategies.
