Ormia Fly: The Original Directional MicrophoneSolving audio focus on a microscopic scale

From the show

Nature Solved It First

Nature mastered the physics of directional sound long before human engineers. The Ormia ochracea fly uses a unique mechanical teeter-totter structure to pinpoint cricket chirps with extreme accuracy, despite having ears less than a millimeter apart. This biological breakthrough inspired modern MEMS microphones, allowing hearing aids to isolate voices in noisy rooms without bulky hardware.
