Base station acoustic source locating system analysis and design

As a fact, when sound wave generated from an acoustic source transmits through the air, its frequency and intensity will be attenuated which depends on the propagation distance. The speed of sound is also affected by other factors like temperature. In this paper, three points acoustic receiving base station design approach is studied and reviewed. The acoustic wave receiving circuits is proposed and the algorithm of the acoustic source positioning is analyzed. Some key issues like accuracy, error compensation are addressed.
