What is wrong with the ‘Bracelet of Silence’

Moral questions on Wearable Microphone Jamming and Frequency Jamming in general

“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. Moreover, our device exploits a synergy between ultrasonic jamming and the naturally occurring movements that users induce on their wearable devices (e.g., bracelets) as they gesture or walk. We demonstrate that these movements can blur jamming blind spots and increase jamming coverage. Lastly, our wearable bracelet is built in a ring-layout that allows it to jam in multiple directions. This is beneficial in that it allows our jammer to protect against microphones hidden out of sight. “— Yuxin Chen, Huiying Li, Shan-Yuan Teng, Steven Nagels, Zhijing Li, Pedro Lopes, Ben Y. Zhao, and Haitao Zheng

Jamming Audio as well as many (most?) other frequency bands such as WiFi, GSM, 3G, LTE, etc. are very simple and very illegal.

What’s the problem in jamming?

During a phone interview, Mr. Lopes turned on the bracelet, resulting in static-like white noise for the listener on the other end. — nytimes

Any other concerns?

Is this the last resort?

I redefined the original problem statement and came up with new ideas and prototypes which I am currently working upon.
