This bachelor’s thesis contains the analysis and results of the system for automatic measurement of noise source direction in the external urban surroundings, describing the findings using the measurement system, the extracts, and the conclusions of these measurements. It involves measuring the direction of the system in different frequency ranges under the controlled conditions in an anechoic chamber. The purpose of the thesis was to observe how the system operates in a free sound field with multiple directed noise sources and the resolution with which it detects those sources, with the intent to convey the gathered information into a more understandable form that can then be compared with manual measurements on a standardized meter. The task, therefore, analyzes the possibility of automating the measurement of noise in the environment based on spatial filtering of sound sources. Therefore, the system was set together with a control computing unit in a carefully selected area where measurements of different noise sources were carried out in order to determine their direction and the impact they have on the main observed source as well as the influence of multiple sources on the behavior of the system. After the measurements, it was determined that the system offers effective and precise determination and separation of the effects of the measured sources. It can also process and present the gathered information in an easily comprehensible way.
