The working principle of cell phone jammer is to emit ultrasonic waves with random noises that cannot be perceived by human ears. When digital devices such as mobile phones are recording, these noises and normal conversation sounds are recorded into the digital device together, making the recorded audio invalid. The audio information in the video also has the same interference effect. Since the ultrasonic noise is randomly generated and cannot be restored, the audio after interference cannot be restored, thus ensuring that the original information is not leaked and spread.
