Sound Camera 6/15/17 This was my senior project in ECE- a microphone array that detects the direction which sound comes from. The goal was to localize sound and display it on a 2d array, just like a camera does with light. Sound sources and reflections light up with a color depending on their frequency, and this can be overlayed on video. You can use this to locate sound sources, or you can even use this as a passive or active sonar, given a sound source. Sound Camera Design
Acoustic Simulation 6/15/17 This adapted code runs an acoustic simulator with open boundaries. Each pixel is a simulated cell, through which pressure and fluid can flow. The open border is achieved with a Perfectly Matched Layer. This was all derived from the acoustic wave equation. On load 10 point sources are randomly distributed. Double click to pause the simulation. Sound Camera
