Popis:	This paper presents an experimental procedure for determining the probability density function of incident noise energy angular distribution at the building envelope using a microphone array as a measuring device. The motivation for this analysis is the development of a methodology which would provide an insight into the actual structure of the sound field impeding the facades in urban environments. The procedure is based on spatial source localization using a microphone array mounted on the building facade. The results are presented for one characteristic situation in an urban area using different algorithms for space-time signal processing. It is assumed that measurements in different types of facade surroundings, such as canyon and non-canyon streets, would point to the specificities of energy distributions which can be expected in the given situations.
