[0037] Such as Figure 1-3 As shown, the present invention relates to the study of acoustic event detection methods, especially noise data in hospital environments. The specific steps include the following steps.
[0038] in the training phase.
[0039] 1. Firstly, the hospital noise is comprehensively analyzed. The present invention detects and classifies various acoustic events in the hospital. The sound data of medical equipment includes: ventilator, ECG monitor, cardiac defibrillation and pacing equipment, and the sound of nursing car movement , including: printer, patient crying, a total of six kinds of acoustic events to be detected. The data includes 100 each, each event length is not less than 1 second, and the audio length is more than ten seconds. The target sound event categories are selected according to their frequency of occurrence in the original annotation and the number of different records in which they appear. The dataset divides the data into training an...
