A Noise Reduction Method of Bird Songs Based on Improved Adaptive Kalman Filtering

In island wetlands， the acoustic environment is complex， with various noise sources such as wind， rain， and ocean waves. To effectively address these interferences in bird song processing and improve the accuracy of species identification， a noise reduction method based on adaptive Kalman filtering...
