Audible Enclave
Context
A recent study demonstrated a new method of producing "audible enclaves" — focused sound zones audible only at specific points, using intersecting ultrasonic beams.
What is an Audible Enclave?
- An audible enclave is a small, confined zone in space where sound is clearly audible to a person within it — but completely undetectable to those outside.
- The sound is audible only to people inside that specific area, while remaining inaudible to others around.
- Technology used:
- Sound is a wave, it moves through a medium (like air) by vibrating the particles back and forth.
- The audible enclave technology is based on non-linear acoustics and sound wave modulation.
- It uses two high-frequency (ultrasonic) sound waves of different frequencies. These waves are inaudible individually.
- When they intersect, they create an audible sound at that point through non-linear interaction.
- The sound is confined to a narrow area — the audible enclave.
