Investigation of possible minimization of number of measurement points in 2D acoustic field reconstruction

Abstract

This study investigates the dependency of accuracy of 2D field reconstruction on the number of points of measurement. To create a mathematical model, a regression equation was used and to evaluate the accuracy of reconstruction the sum of residual squares was used. The adequacy of the final model was evaluated by the Fisher criterion. It was shown that the accuracy of the mathematical model logarithmically depends on the number of points of measurement, whose results were used to form the mathematical model.
