Researchers devise a way to levitate small objects from reflective surfaces using sound waves TechSpot

As Science Alert highlights, engineers Shota Kondo and Kan Okubo from the Tokyo Metropolitan University split a transducer array into blocks, making it more manageable. Next, they employed an inverse filter to recreate sounds based on the acoustic waveform, which makes it easier to tweak the phase and amplitude of...
