Microphone arrays for beamforming
Grénar, Milan ; Smékal, Zdeněk (referee) ; Míča, Ivan (advisor)
The aim of the bachelor's thesis is to assemble theoretical and practical information about methods for estimate direction of arrival whereas there is an emphasis on beamforming. There are introduced general conventions which are being used to measure with multichannel microphone array. Part of this thesis is the implementation of the DAS beamformer in several modifications, including verification of the functionality in ideal and real conditions.

Design and testing of the system for localizing a sound source
Havelka, Martin ; Vechetová, Jana (referee) ; Najman, Jan (advisor)
This bachelor’s thesis deals with possibilities of sound source localization. There are generally mentioned possible hardware and software solutions at the beginning, from which two applicable methods and suitable components of test device are selected. Further there is a practical part of this work, where programmed algorithms are described. An essential part is testing. Accuracy is tested for the selected microphone array, depending on the change in the number and position of the sensors, the effect of ambient noise, and the location of the obstacle in the area. The output of the tests is the evaluation of functionality and accuracy for both methods used.
