AB  - The goal of the project described in this paper was to design an acoustic system for localization of the dominant noise source by implementation of the conventional delay-and-sum beamforming algorithm on FPGA platform with a sound receiver system based on digital MEMS microphone array. The system consists of a platform for acoustic signal acquisition and data processing (microphone array, interface, and central block), and a platform for monitoring and control (a computer with a user application). Such configuration provides the execution of the beamforming algorithm in real time. Additionally, FPGAs are bringing many benefits in terms of safety, reliability, rapidity, and power consumption. The platform was tested and verified with various microphone array configurations and results are presented in the paper.
