The key vulnerability? No microphone is perfect. When two very loud sounds enter a mic, they don't just add up; they multiply, creating new, artificial frequencies called "intermodulation products." A smart jammer exploits this physical limitation.
Why ultrasonic? Because the human ear can barely hear above 20 kHz. To you, the room is silent. But to a cheap microphone (which can physically respond up to ~25 kHz), the room is absolute pandemonium.
The audio jammer is less of a "silencer" and more of a . It exploits a hidden flaw in cheap hardware using frequencies we cannot perceive. It is a brilliant, narrow-spectrum weapon against unsophisticated eavesdroppers. However, against a professional with a high-end, linear microphone, the jammer is about as effective as whispering to a person wearing concrete earplugs.
