Over the last few decades, acoustic beamforming methods with phased microphone arrays have gained increasing attention from both industries and research institutes, providing a practical tool for acoustic-field investigations in wind-tunnel tests and achieving accurate results. The purpose of this Master Thesis is to provide a detailed overview of the main beamforming algorithms for the localization and quantification of sound sources generated by rotating machines, such as wind turbines, low-pressure fans, and low-speed propellers, as well as a thorough understanding of their potential and inner limits. The time-domain ROtating Source Identifier (ROSI) method and the frequency-domain Virtual Rotating Array Method (VRAM) method are currently the most widely used beamforming techniques in the acoustic community.
