In recent decades it found its acoustic application through the development of acoustic camera and holography. This paper demonstrates the example of near-field beamforming. Eight low-cost microphones array was built and used for signal acquisition and spatial filtering is done by dedicated software. Despite the modest price of hardware components obtained results are solid and accurate.Read More
