MyNoise Ultrasonic Sound Blocker

It works in such a way that it chokes up the microphone by ultrasound, thus making it impossible to make any recordings. In comparison to usual noise generator, the ultrasound interference is advantageous in the fact that the interference lacks any audible noise as adults are insensitive to it to a large degree.
