Estimation of the Amplitude–Frequency Response of a Sound Source from Measurements in a Tank with Reflecting Boundaries

The article presents the results of a laboratory experiment testing a method for reconstructing a sound field excited by a calibrated source in the free space from measurements of a field excited by the same source in a tank with reflecting boundaries. The reconstruction procedure uses a standard acoustic monopole and compares the fields emitted by it from specially selected points of the tank with the field of the calibrated source. In the experiment, the frequency dependence of the field intensity of the calibrated source averaged over a sphere of large radius was evaluated.
