[0051] refer to figure 2 , figure 2 It is the first embodiment of the training method of the abnormal sound detection model of the present invention, the training method of the abnormal sound detection model includes the following steps:
[0052] In step S110, the sound segment with a preset duration is cut into N sub-segments, and each sub-segment is sampled and filtered by H band-pass filters of different frequency bands to obtain W sample values, forming a three-dimensional feature sheet of N×H×W quantity.
[0053] In this embodiment, abnormal sound detection refers to detecting abnormal sounds in different application scenarios. For example, abnormal sounds in real life include but are not limited to gunshots, explosions, cries, screams, and the like. For different application scenarios, the application of abnormal sound detection will also be different, and no limitation is made here. Abnormal sound detection is realized through a trained abnormal sound detection mod...
