摘要

If microphone arrays are to be used in acoustic testing, a signal processing method must be applied to produce measurement results such as spectra and location of sources from the data. It is well know that different processing methods may produce different results, so the practical question arises which method to choose. We propose some strategies that allow for the a-priori choice of the most suitable processing method from the raw measured data. One method uses the eigenvalue spectrum of the measured cross spectral matrix while another is based on the classical beamformer output and a convolutional neural network. After estimating the apparent number of sources and the dynamic range, the best method is looked up based on the statistical analysis of a large number of synthetic test cases. The procedure is demonstrated using a practical example.
