Embodiment Construction
[0079] In this embodiment, the method for reconstructing a moving sound source using the moving equivalent source method is carried out as follows:
[0080] 1. See Figure 1a and Figure 1b , using a microphone array to measure sound pressure information containing the Doppler effect on the measurement surface H;
[0081] 2. See Figure 1a and Figure 1b , set the virtual source surface S inside the moving sound source * , and there are moving equivalent sources distributed on the virtual source surface, and the number of moving equivalent sources is not greater than the number of network points on the corresponding measurement surface; the moving equivalent source is a moving monopole sound source, and its frequency-domain radiation sound pressure expression is
[0082] g ‾ ( r , r oj ) = exp ...
