Wearable Microphone Jamming
sandlab.cs.uchicago.edu
We engineered a wearable microphone jammer that is capable of disabling microphones in its user’s surroundings, including hidden microphones. Our device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range.
I love this project so much—the research & concept, the 3D printed parts, the off-the-shelf components, and that it’s open sourced on GitHub.
