Application of Sound Enhancement Technology in the Calibration of Electrical Instruments and Meters
This paper discusses the application of sound enhancement technology in the metrological verification of electrical instruments.Through adaptive filtering,wavelet transform,deep learning and other signal processing methods,the acoustic analysis of environmental noise filtering,mechanical component state monitoring and metrological verification is realized.Experiments show that the noise suppression degree,vibration feature extraction accuracy and metering event recognition rate are improved by 137.3%,23.1%and 19.1%respectively,which significantly improves the accuracy and reliability of metering verification.
