The Design of Sound Source Localization System Based On STM32

A sound source localization system is designed using STM32F103ZET6 microcomputer, OLED display module, sound acquisition module, 2D steering gear gimbal and laser head. This system can not only locate and display the sound source, but also adjust the sensitivity of the sound source acquisition module to realize the screening effect of sound source size. The system measures and calculates the distance and angle of sound source for many times, and screens out the positions of different sizes of sound, all of which meet the project requirements and the error is within the ideal range.
