The purpose of presented master thesis is to learn about the theory of aeroacoustics, design, construction and testing of a laboratory test room. The latter will enable further research in the field of aeroacoustics, psychoacoustics and a basic understanding of the formation of turbulence and related noise. When designing the aeroacoustic flow channel, it was necessary to specially design the test part, the drive part, choose suitable acoustic insulation, and ensure the accuracy of the measurements. It was necessary to develop and write a software for locating sound sources and drawing an acoustic image. Using an analytical and numerical approach, individual parts of the test facility were first designed. The two approaches were compared with each other and showed strong agreement. After obtaining the resistance characteristic, the driving machine of the testing room and the acoustic insulation were also selected. In parallel, the development of the algorithm for locating sources of aerodynamic noise with the help of beamforming took place. After construction, measurements were taken in the test section, which were compared with an acoustic camera. The results show a good agreement between the results, but at the same time they raise new questions related to the generation of aerodynamic noise.
