Originální abstrakt

This text deals with simulation, comparison and optimisation of different methods for near field array visualisation of the sound fields. These methods are based on principles of the Near Field Acoustical Holography (NAH). All simulations are realised in MATLAB environment. For the good comparison and optimisation of the methods, a realistic model of vibrating surface has been developed. The main interest is focused on the precision of the sound pressure field estimation, calculating time and sensitivity to the measurement errors for different NAH methods and algorithms. Realistic conditions are used for the simulations. The vibrating surface and its radiation is described at the first. The detailed description of different methods and their optimisation follows, and after this all presented methods are compared.
