The most sensitive, confidential communications are best done in person. Even then, it can be hard to trust that your own devices aren't spying on you. The Hushbox can ensure that's what's said in private stays in private. It uses an array of up to 30 ultrasonic transducers to jam any microphone within the box, eliminating the risk of audio leaks and rendering any potential recordings unusable. When putting all devices inside the box isn't possible, it can be left open with the array pointed at a specific target for directional jamming, or otherwise used to block any AI-based "helpers" in the room like Alexa, Google, Siri, etc. from hearing a single word.
