Application of Kalman filtering to acoustic sound diagnostic measurement

Application of Kalman filtering theory to data processing is a well-known. Many books and articles is devoted to radar targets tracking, as classic example we introduce, as a book more different applications can by introduced. The development theory and practice continues and we would like present one possible new application. The paper deals with problems of Kalman filter application to acoustic sound diagnostic measurement. The approaches are aimed to measurement data processing. There are results of application to the real acoustic signals of car engine are presented.
