[0055] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.
[0056] Combine figure 1 , The present invention proposes a rain sound signal noise reduction processing method, the method includes:
[0057] Collect real-time sound signals during rain, and the real-time sound signals include at least real-time rain sound signals.
[0058] Based on the rain sound separation subsystem that removes the real-time first environmental sound signal and the real-time second environmental sound signal from the mixed sound signal, separates the rain sound signal without the environmental sound signal from the real-time sound signal; the environmental sound signal includes The first environmental sound signal and the second environmental sound signal.
[0059] In a further embodiment, the method further includes:
[0060] Determine the rainfall level according to the frequency spectrum of ...
