• TITLE: RADIATION PATTERN MEASUREMENT WITH MATLAB IMPLEMENTATION
• AUTHOR(S): H. Zhivomirov, I. Iliev
• ABSTRACT: In the present paper a Matlab®-based program is developed for measuring the radiation pattern (polar response) of the loudspeaker using data acquisition system NI USB-6211, Matlab® Data Acquisition Toolbox and Matlab® Signal Processing Toolbox. A definition of the loudspeaker radiation pattern is presented along with block diagrams of the measurement setup and the program algorithm. A comparison between the theoretical and the experimental results has been made. Conclusions are drawn from the analysis of the study. The proposed Matlab® program can be downloaded for free, from the link given at the end of the paper.
