Researchers Develop Acoustic Touch Technology That Helps Vision Impaired See Using Sound

Technology

Acoustic levitation is a remarkable phenomenon where sound waves are used to suspend objects in mid-air. This is achieved by generating high-frequency sound waves that create standing waves with nodes and antinodes. The pressure from these waves counteracts gravity, allowing objects to hover at the points where the upward pressure balances the object's weight. While the concept may sound futuristic, there is speculation that ancient civilizations, like the Italians during the Roman era, might ha
