RoomNoise Ultrasonic Sound Blocker

The device works in such a way that it chokes up a microphone by appropriately generated ultrasound frequencies, thus limiting the input amplifier of the recording device. The frequency combination is generated particularly to eliminate local spots with low ultrasound intensity, which increases efficiency of the interference greatly.
