Acoustic signal contains information on the state of mechanical motion. but the disadvantage of low signal-to-noise ratio (SNR) is that acoustic signal without noise reduction is difficult to apply to fault diagnosis directly. This study proposes an adaptive noise reduction method based on the dislocation superposition method (DSM). which can realize automatic noise reduction for acou... https://chefesquipmenters.shop/product-category/water-filtration-systems/
