The process of the determining the sound source direction and based
on the method of passive acoustic location are considered.
A small-sized device based on the Orange Pi Zero single-board minicomputer
and sound sensors based on the LM393 amplifier has been developed. This device can
be built into existing lighting systems with the design of regular Platonic polyhedra.
Options for the sound sensors placement on the plane and in 3D space which decrease
the computational complexity of the problem due to the spatial placement of the
microcontroller system based on Platonic solids are proposed.
The software application for the offered information system of passive acoustic
location (ISPAL) is developed on the basis of classical three-link architecture, contains
backend and frontend components. The user interface (UI) for web and mobile versions
of software are developed.
The possibility of military-civilian use of the developed information system is
considered.
