Sound Fences That Only Youth Hear

The Mosquito is an electronic device that acts like a sonic fence. It emits a high-pitched frequency specifically designed to be audible only to young people, causing them discomfort to discourage loitering in public areas.

As humans age, the ear naturally loses the ability to perceive very high frequencies, a phenomenon that this device cleverly exploits. By targeting the sensitive hearing range of teenagers, business owners can clear crowds without bothering older adults. While marketed as a security tool, it has sparked significant debate regarding its impact on young people and public space accessibility. It serves as a strange reminder of how our biology changes over time.
