Ultrasonic bracelet jams hidden microphones around you

[Media]

A prototype bracelet omnidirectionally jams and eliminates blind spots (where transducers cancel each other out) through wrist movement. It's more effective than dedicated stationary jammers because it scrambles hidden mics.

This is ideal for anyone who does not want to be eavesdropped on by voice assistants, spies and hidden mics, especially for people who tend to move from room to room. If worn in public, it would create havoc with phone calls and other mic-dependent devices.

While this device keeps meetings secret, it could also help politicians avoid accountability during secret...

In the legal sense and contrary to popular belief, this is NOT a jammer. It doesn't transmit any RF signal (electromagnetic). It only transmits an accoustic signal (sound, literally air vibrations). Its frequency has nothing to do with what type of signal it is. It just happens to be sound with a frequency too high to be heard by a human ear. Because this signal is mechanical, rather than electromagnetic, it isn't legally classified as a jammer, so the FCC has no legal jurisdiction to regulate it. As such, using it isn't illegal, though if it did interfere with a 911 call and somebody died, you could still be sued by their family for "wrongful death" (and if proved it was intentional, you could end up being arrested on a standard murder charge). You won't be fined or jailed for simply using one though.

Not very stealthy though

Nissan had a device they used in prototype vehicles which was a type of speaker. It emitted opposing sounds which were used to cancel out the sounds from the engine, tyres etc. It basically made the car silent. It worked, but it was so effective it was deemed unsafe. Pedestrians could not hear the car coming. They put the whole thing on the shelf.

If you are worried about being recorded make sure the person you are talking to does not have a cell phone. Now days the average bug phone is recording front and back and audio all at once. The recorders are using digital tech so not really transmitting like old school bugs. However there are exceptions. This is when simple homemade devices can pick up those radio freqs. Best advice dont do anything illegal. If you really want to have a he said she said conversation get nude or get in the hot tub. Any little widget can be a bug. Again don’t do anything illegal.
