Abstract
A method and system provides for acoustic sensing of structures, including a general shape and/or configuration of the structure and movement within the structure. Acoustic waves are used to characterize structures, including any activity within. As waves from a sound source travel into the structure, they resonate within cavities and connecting tunnels or halls. This acoustic resonance is received at an acoustic receiver. The received signal is analyzed in comparison to the generated signal, and properties of the structure are determined, including the size and shape of the structure, as well as movement of objects within the structure.
