The objective of our project, the Acoustic Camera, is to develop a device that accurately identifies the origins of surrounding sounds. Unlike light, which travels in straight lines and allows for straightforward source detection, sound propagates in waves, complicating the determination of its direction and source location.

Our solution leverages the phase information of sound waves. By measuring the sound from multiple locations and analyzing the phase differences, we can accurately calculate the direction from which the sound originates.

Our design incorporates the following components: 32 microphones, a camera, an FPGA (Field-Programmable Gate Array), a computer program, and a microcontroller. The microphones are strategically placed on a PCB (Printed Circuit Board) to optimize performance for the specific frequencies we are targeting. The FPGA is programmed to handle parallel data processing at the working frequency, while the microcontroller wirelessly transmits data from the FPGA to a computer. The computer then calculates the sound's location, which is visually represented on an image captured by the camera.
