Beschreibung
Zusammenfassung:	The present invention discloses an item locating and finding method, system and device based on acoustic signal, which relates to the field of item location, and aims at solving the problems in the prior art that a specific directional angle of the item cannot be detected and the technical solutions in the prior art are not suitable for common intelligent terminals and are greatly affected by the environmental noise; performing unilateral and bidirectional ranging based on the acoustic signal; and performing location by using acoustic ranging and PDR.
